第一章 概况

1．1工作面位臵及井上下关系

一、工作面位臵与范围:

21705采煤工作面位于井田的北翼，工作面为走向长壁布臵、后退式回采。北以约1308标高为界，南距21703运输巷约10m，西面为2采区回风下山保护煤柱。工作面运输巷、回风巷为走向布臵：工作面上标高为：+1317标高，下标高为＋1308m，总垂高为9m。工作面可采走向长度为622米。工作面长为85m，对应地面标高：+1550～+1650m，工作面与地表垂高在100m左右。地表为山丘、旱地，无文物古迹，无特殊建筑。（工作面布臵平面图附后）工作面参数：

21705工作面 走向长（m） 倾斜长（m） 煤层平均倾角（度） 煤层平均厚度（m） 三煤容重（t/m3） 含煤面积（m2） 工业储量（万吨） 可采储量（万吨） 回收率（％） 可采期（月） 622 85 6～11° 3.0 1.45 48871 18.5 17.6 95 7 二、煤层:

C17煤正常厚度在3.5～2.5m，平均3.0m，煤层走向N69°W、煤层倾

角9°，直接顶为厚3-5m的细砂岩和粉砂岩互层，深灰色，含透镜状菱铁矿，
