| 摘 要： | 2021B工 作面 是我矿 二水平 12-1煤 层的首 采工 作面,区 域地 质条件 复杂 ,断层 极为发 育。掘 进过 程中通 过对断层延 伸长 度、落 差的综 合分 析,采用 巷探 、钻探、物探等 手段 加以验 证,顺 利 实现 了工 作 面对 FE12、FE9'、FE105等断层的剥 压改 造,圈 出了走 向长 度达 800余 m 的综 采工 作面,控 制了 断层的 赋存 形态,为 2021B 工作 面 的采 掘及 周 边工程的规 划创 造了有 利条 件。

| Abstract: | The No. 2021B working face is the initial working face in No.12-1 coal seam. Regional geological condition is complicated and fault is fairly developed. Analyses was made to fault extent and throw during heading advancing, then proving by the means of tunneling prospecting, drilling and geophysical prospecting. Realized the working face lebensraum between Nos. FE12, FE9', FE105 faults, blocked out a fully mechanized mining working face of 800 more meters long strikingly. The occurrence of faults were controlled, it create advantage for No.2021B working face winning and opening, as well as programming of periphery engineering. |
