牛马司煤矿是湖南省主要的主焦煤产地。娄(底)邵(阳)铁路支线从东到西横贯井田,共压煤105万吨。经铁路部门与煤矿共同协商研究,决定以牛马司煤矿二工区1128工作面作试点,进行铁路下采煤的试验。1128工作面走向长350米～400米,倾斜长100米,风巷离地表垂深230米,溜子道离地表垂深270米,平均开采深度为250米。煤层厚2.1米,倾角21°,采用走向长壁采煤法开采,全陷法管理顶板。上复岩层主要为灰岩,其次为砂岩和页岩。受开采影响区段的线路位于工作面下边界附近,大致沿煤层走向方向延伸。线
Cattle Magu mine is the main coking coal in Hunan Province. Lou (bottom) Shao (Yang) Railway Extension traverses the field from east to west, a total of 105 million tons of coal. After consultation with the coal mine, the railway department and the coal mine decided to test the 1128 working face of No.2 Work Area of Niumasi Coal Mine and carry out the test of coal mining under the railway. 1128 face to 350 meters long to 400 meters long, inclined 100 meters long, the wind lane 230 meters deep from the surface, slippery walkway 270 meters deep from the surface, the average depth of exploitation of 250 meters. Seam thickness of 2.1 meters, dip 21 °, the use of long-wall mining method to mining, all-sink management of the roof. The upper strata are mainly limestone, followed by sandstone and shale. Affected by the mining section of the line is located near the lower boundary of the face, extending along the direction of the coal seam. line
