【摘要】：分析了路天煤礦041606工作面水文地質(zhì)條件,確定了充水水源主要為16號煤層頂板基巖裂隙承壓水,頂板采動破壞帶及斷層為主要導(dǎo)水通道。采用鉆探探放水、水化學(xué)測試分析、水文地質(zhì)調(diào)查、測繪等手段對041606工作面回風(fēng)巷斷層出水水源進(jìn)行了綜合探查,從來水方向、水壓、水化學(xué)特征離子綜合判別出水水源為頂板基巖裂隙承壓水和041604采空區(qū)積水共同作用所致,與F公逆斷層二采區(qū)剝采坑積水無直接水力聯(lián)系�；趯ο锏肋^斷層面的總水量分析及探放水鉆孔引流效果評價,認(rèn)為回風(fēng)巷掘進(jìn)前方斷層導(dǎo)水不會對巷道掘進(jìn)構(gòu)成威脅。
[Abstract]:The hydrogeological conditions of No. 041606 working face in Lutian Coal Mine are analyzed. It is determined that the water source of water filling is mainly confined water from the fissure of roof rock of coal seam No. 16, and that the failure zone of roof mining and fault are the main channel of water diversion. By means of drilling water exploration, hydrochemical test and analysis, hydrogeological investigation and surveying and mapping, this paper makes a comprehensive exploration of the outlet water source of the fault in the return wind lane of 041606 working face, and the direction and pressure of the water are obtained. The water chemistry characteristic ion synthetically discriminates that the outlet water source is caused by the joint action of the roof bedrock fissure confined water and the 041604 goaf water, and has no direct hydraulic relation with the stripping pit water in the second mining area of F Gongreverse fault. Based on the analysis of the total water quantity of the roadway passing through the fault plane and the evaluation of the drainage effect of the drilling hole, it is considered that the fault water diversion in front of the backwind roadway excavation will not pose a threat to the roadway excavation.
