摘要
在煤矿开采中,水害防治至关重要。文章以铁生沟煤矿14141采面的水害防治为例探讨了在煤矿开采中的有关技术问题,提出了利用物探的坑透、直流电法和音频透视法,先行发现断层、裂隙破碎带,然后利用钻探对物探异常区段施钻,验证物探结果,探明顶板含水情况,为顺利开采提供依据。
The prevention and cure of flood is essential in coal mining. In this paper, taking the prevention and cure of flood at 14141 face in Tiesheng Coal Mine as an example, the relevant trechical problems in coal mining are discussed. The probing, DC way, and audio - frequency perspective way are pointed out. The faults and fractured broken are first discoveryed, then the drilling geophysical prospecting is used to drill in the unusual geophysical prospecting section. The geophysical prospecting result is checked. The roof aquifer situation is verified. The basis is provided for the successful exploitation.
