摘要
孙村煤矿通过宽线二维地震勘探、跨孔电磁波CT,精细化探查了边界煤柱存在的薄弱区域,进行精准注浆,并通过跨孔电磁波CT、钻孔取芯手段对注浆效果进行了评价,形成了集矿界断层煤柱薄弱区探测、注浆加固过程控制与注浆效果检测于一体的侧向高位积水复杂矿井煤柱水害预防技术体系,对保障相邻生产矿井安全生产,防止突水灾害发生具有重要意义。
Suncun Coal Mine finely explored the weak areas of boundary coal pillars through wide line 2D seismic exploration and cross hole electromagnetic wave CT,and conducted precise grouting.The grouting effect is evaluated through cross hole electromagnetic wave CT and drilling coring methods,forming a technical system for preventing coal pillars water damage in complex mines due to lateral high water accumulation that integrates detection of thin and weak areas of fault coal pillars,control of grouting reinforcement process,and detection of grouting effect,it is of great significance to ensure the safety production of adjacent production mines and prevent the occurrence of water inrush disasters.
