【摘要】 老窑水隐蔽性强，是矿山绿色开采的难题。以铁迈煤矿为例，提出“探查锁区、钻探释危、复核查验、钻护固安”的综合治理措施。通过直流电法及钻探的立体探测，明确了顶板30～50 m为顶板老窑采空区，主要为老窑积水，0～30 m为裂隙水区，50～80 m为冒裂影响区裂隙水。其次，将物探的异常区进行了等级划分，针对各异常富水程度，从钻孔的布置密度、倾角、间距等参数进行了优化设计。11050工作面疏放水技术中，累计疏放顶板水132 262 m~3，裂隙水占25.25%，老窑水占39.94%，相邻工作面积水34.81%。最后，通过矿井瞬变电磁法的复测，整体异常特征区及范围明显减小，个别钻孔的单孔涌水量低于2 m~3/h，满足矿井排水能力。更多还原

【Abstract】 Old mine water, with its strong concealment, poses a challenge to green mining. Taking Tiemai coal mine as an example, proposes an integrated management strategy of "survey and lock area,drilling for danger relief, re-inspection and verification, and drilling for reinforcement and safety".Through three-dimensional detection using the direct current method and drilling, it was identified that the 30-50 m range above the roof is an old mine goaf, mainly consisting of accumulated old mine water, the 0-30 m range is a fracture water zone, and the 50-80 m range is a fracture water area affected by roof burst. Secondly, the anomaly areas from geophysical surveys were graded, and an optimized design was carried out for parameters such as drilling layout density, inclination, and spacing according to the degree of water richness in each anomaly area. In the dewatering technology of the 11050 working face, a total of 132 262 m~3 of roof water was drained, with fracture water accounting for 25.25%, old mine water for 39.94%, and adjacent working face water for 34.81%. Finally, a re-measurement using mine transient electromagnetic method showed a significant reduction in the overall anomaly characteristic areas and ranges, with individual drilling holes having a water inflow rate lower than 2 m~3/h,meeting the mine′s drainage capacity.更多还原
