摘要
麻家梁矿14101首采工作面斜长为250 m,顶板富水性强,为防止盲目揭露构造造成透水事故,采用大透距坑透仪对该采煤工作面进行了探测,探测结果中的异常区与实际揭露情况基本一致,并总结了探测时应注意的事项。
The length of the first mining face is 250 m in the Majialiang mine 14101, and there is much water in the roof. For avoiding water inrush accident because of destroying construction ignorantly, the coal-face is detected with the pit through instrument of the large penetration distance and the results showes that the situations of the anomalous are almost the same with the real. area
