摘要
急倾斜煤层开采形成的采空区水患问题是主要灾害之一。地下水系统中的渗流具有非线性特征。随采深增加,渗水半径与渗流量加大,给安全生产带来威胁。以铁厂沟煤矿+645水平45#煤层掘进工作面探放水为例,通过现场开采情况调查,采用矿用坑道钻机进行探查预计,确保矿井安全掘进及生产,为开采扰动范围灾变预报和控制提供了借鉴。
The historical mining for steep coal seam had formed many mined-out-area in Wulumuqi coal region. The problem of flooding was one of the major sources of disaster. With the increasing of mining depth, water seepage radius increased, the amount of water seepage also increased, which even brought to risk for the safe production. Taking the working face of ＋ 645 m of No. 45 seam at Tiechanggou coal mine as an example, the prediction and drainage were applied to the tunneling. Based on field surveys and co ensure mprehensive analysis of the exploitation, the tunnel drilling rigs for exploration were applied to the safe tunneling and production. This provides a reference for prediction and control in the disturbed zone.
