SUMMARY
This report tabulates respirable dust concentrations andcomments on the composition of the dust at South KirkbyColliery for the period April 1976 to March 1977.Information is given on methods of working, output andmanpower.
'Total1 dust concentrations are tabulated and those forface sites were, on average, nine times as high as therespirable dust concentrations.
The colliery had a coalface mean respirable dust concen-tration of 3. 4 mg/m3 the same as the previous year. Themean ash content of the respirable dust was 59. 4 per centand the mean quartz content in sample 8. 9 per cent(concentration 0. 30 mg/m3).

1. INTRODUCTION
This report lists and describes environmental measurements madein the four seams worked at South Kirby Colliery during the periodApril, 1976 to March 1977. As in previous years the dust measure-ments were made with the Gravimetric Dust Sampler, Type 113A.
The dust values are presented in a series of charts or tables; thosefor production faces listing concentrations by site and occupation.Information is also provided on the composition of the respirable dust,the mining methods and conditions.
The relationship between dust concentrations on the face and at thecontrol point in the return is examined and the ratio of 'total1 torespirable fraction in the dust cloud is noted.
2. SOUTH KIRKBY COLLIERY
The colliery is located in the Barnsley Area on the exposed part ofthe Yorkshire Coalfield.
2. 1 Seams worked and coal outputs
The Beamshaw (03:230)*, Meltonfield (03:150), Dunsil (03:340) andNew Hill (03:140) Seams continued to be worked. Ten coalfaces,eight advancing and two retreat units were in production (not allsimultaneously). In the New Hill Seam, an advancing face (E. 11),the first in that seam, commenced production.
Table 1, at the end of the report, gives quarterly outputs, in sale-.able tons, by face and seam. Coal output decreased by about 25 percent with the largest proportion of the total output being produced bythe New Hill Seam (42 per cent) and not the Meltonfield Seam as inprevious years.
2. 2 Ventilation, temperatures and dust suppression
Air quantity measurements in intake roads, nine metres outbye ofcoalfaces, were obtained from the colliery records. The tempera-tures and relative humidities are the means of measurements madeby investigators at various face positions. Dust suppression methodswere similar to those previously reported (Mills & Annis, 1978) and
* National Correlation Code.
2.
.details are given in the face charts (Tables 2 to 11, Section 4,pages • .
2. 3 Dust respirators
Martindale respirators (Types U and Y) continued to be freelyavailable to all workmen and respirator cleansing was as describedpreviously (Mills; Thorpe & Annis, 1974). In a four week periodin October, 1976, 294 respirators were in use compared with398 for a similar period in 1975.
2. 4 Manpower distribution and occupational grouping
\-The stratification.of the. colliery work.fo.rce was.as described previously(Mills & Thorpe, 1971). The number of occupational groups availablefor sampling was as follows.:.-
Face 51Elsewhere underground .33Surface 1
At March, 1976, 1 791 men were employed at the colliery comprising637 faceworkers,' 797 others and 328 surface, workers. The numberof faceworkers employed at March, 1975 was 740.
3. SAMPLING AND EVALUATION
The methods of'sampling, evaluation and compositional analysis were.as described previously. (Harrison, 1972 and 1974, Mills and Thorpe,1971, Mills, Thorpe & Annis, 1976).
Table 12, folio wing ^ shows the distribution of sampling effort.

The total of 1, 365 samples include several underground observationsby investigators. In addition 59 samples were rejected as unsatis-factory due to instrument failure etc.
The decrease in the number of faceworkers employed at the collieryresulted in a decrease in the number of face observations (622samples in 1975).
4. RESULTS AND DISCUSSION
4. 1 Faceworkers
The face summary charts (Tables 2-11) show the mean concentrationsof respirable dust in each quarter of the year.. The mean ash andquartz concentrations are given by working site. The overall facemean respirable dust concentrations are calculated from the sitemeans weighted by the number of men working at each site.
4. 1. 1 Advancing faces Table 13, following, gives mean concen-trations by site weighted by the number of men per face site, forthe years, 1974, 1975 and 1976. '

For explanation of site numbers see Table 2 (page 4). .Intakedust levels tend to be similar to those of the previous yearwith the. exception of the value for site 2. The cpncentr.ationof 3. 4 mg/rn^ for this site:is weighted by nine observationsfrom D08 face intake Dpsco -In-seam Loader, which gave a;rrfeainconcentration o f 5 . 8 m.g/m3. " . • * ' • • •
4. 1. 2 Retreat faces' (New Hill Seam) The overall mean concentrationof 3. 7 mg/m3 (91 samples) was the same as the previous year. Thehigher individual observations generally tended to occur on E06 coal-face where coal output was nearly twice that of E05 face, and whereadditional floor dirt was being worked.
4. 1. 3 Faceworkers common to seam or colliery Table 14 follows andsummarises the mean concentrations for the four occupational groupsconcerned.

The relatively high value for the Meltonfield Face ConveyorAttendants is partly due to a single observation of 11. 4 mg/m3,from BIO face on a shift when four other larger then averageconcentrations were reported.
4. 2 Development workers
The dust concentrations are given in Table 15 at the end of thereport. The major development, Barnsley Access, was fromthe Highfields drifts where a pair of roadways using DoscoRoadheaders continued to be driven on the Beamshaw horizon,to enable re-entry to the Barnsley Seam to be made through amajor fault. The overall mean dust concentration in theseheadings and associated workings was 3. 2 mg/m3 (64 samples).
In the Beamshaw Seam, development of DOS face was completedusing a Bretby In-seam Miner to drive the face heading. Themean respirable dust value of 5. 8 mg/m3 (15 samples) revealeda high quartz concentration of 0. 95 mg/m3 (16. 4 per cent).
The overall mean respirable dust concentration for all collierydevelopment decreased to 3. 3 mg/m3 (184 samples) from 3. 7 mg/m3
(108 samples, 1975).
The overall mean quartz value of 0. 35 mg/m3 is higher than thatrecorded in 1975 (0. 29 mg/m3).
4. 3 Other non-faceworkers
(Table 16 at end of report). There are no appreciable differences inthe mean values apart from two New Hill groups, Haulage workers,E102 and Salvage workers, E106; the value of 4. l mg/m3 for thelatter group is the highest yet recorded at the colliery for anysalvage group.
The samples in occupational group E77 were again divided into twoparts for analysis, i. e. Diesel Drivers and General Haulage work.Although the ash content of the Diesel Haulage samples wasapproximately the same as the previous year (circa 57 per cent),that for the remainder of the group, the majority of whose sampleswere taken in the vicinity of the Barnsley Access stone headings,increased from 39. 6 per cent (1975) to 72. 3 per cent. In the previousyear the majority of the observations for the General Haulage workwere made in the service areas of Barnsley Seam coalfaces.
4. 4 Environmental summary
Table 21, at end of the report, gives the mean respirable dust,ash and quartz concentrations for coalfaces, development, elsewhereunderground and surface together with the corresponding values forthe previous two years.
The overall power loading mean dust concentration of 3. 4 mg/m3
was lower than that for the preceding year (3. 7 mg/m3). The ashcontent, during power loading operations, ranged from 49. 8 percent (E06 face, New Hill Seam) to 63. 2 per cent (B31 face,Meltonfield Seam).
24.
The mean quartz in ash content for all coalface operations increasedto 14. 9 per cent (13. 2 per cent in 1975) with a tendancy for thehigher values to occur on the Beamshaw faces. The quartz in ashcontent for Beamshaw DOS face ranged from 14. 0 to 18. 5 per centwith the higher contents being observed in the stables and returnroadway.
4. 5 Relationship between control point and mean face concentrations
The mean respirable dust concentrations at control points in facereturn roadways (70 metres outbye) are given in Tables 2rl 1. Theindividual control point to face ratios, Tables 21, varied between1. 05 (B31 face) and 3. 32 (D06 face). The latter ratio is not typicalas it is based on a single control point sample and five face obser-vations made during a period when little work was done at thereturn end of the face (See Table 6).
The overall colliery mean value (calculated as the ratio of the meanof 80 control point to the mean of 440 face observations) is 1. 46 andthe highest, yet recorded; values of 1. 41 and 1. 37 were recorded in1974 and 1975 respectively. The arithmetic mean of the 10 control/faceratios (based on man weighted face means) was 1. 63.
4. 6 'Total* dust measurements
Tables 17 and 18 summarise the 158 total dust determinations madeat coalfaces and elsewhere. In general, and as in previous years,the ratio of 'total1 dust to respirable dust concentrations tended tobe lower at the return ends of faces. The overall mean ratio for thecoalfaces was 8. 9 (11. 3 in 1975) and for the colliery 9. 7.
Eighteen respirable dust samples from four occupational groupswere matched with their corresponding elutriator samples foranalysis (Table 19, opposite).
It is noted that whilst the per cent ash and the compositional resultsvaried, the quartz, kaolin and mica contents of the elutriatorfractions were all lower than their matched respirable sample; thisfollows the pattern of previous years. (Harrison, 1978).
4. 7 Comparison of quartz analyses by direct and standard KBr)methods
Table 20 gives the comparison of the percentage quartz in samplefor the direct method (Dodgson & Whittaker, 1973) and by thestandard (KBrn Disc) method of analysis for face control points andBeamshaw Seam Development headings.
