摘要
通过对赵家寨煤矿12201工作面突水过程及原因的分析,结合赵家寨煤矿水文地质条件,此次注浆堵水工程采用了井下与地面相结合的注浆方案对突水进行治理。在井下布置防水挡沙墙,再针对性地布设地面截流和注浆孔,采用地面注浆与井下疏水降压技术,使12201工作面突水得到了快速、有效的治理。该工程使井下和地面突水治理相结合的方法在注浆堵水中得到充分应用。
Based on the analysis of the water inrush process and causes of the 12201 working face in Zhaojiazhai Coal Mine, combined with the actual hydrogeologieal conditions of Zhaojiazhai Coal Mine, the grouting scheme for the grouting and water plugging engineering was combined with the ground and surface to control the water inrush. At first, the waterproof and sand retaining wall is arranged in the underground, and the ground closure and grouting holes are set against the ground, and the treatment method of ground grouting and un- derground drainage depressurization was carried out. The water inrush of 12201 working face has been quickly and effectively con- trolled. The method of combining the underground and the ground face is fully applied in the grouting water plugging.
