煤电钻技术在探放老空水中的应用

Technical Probe into Electric Coal Drill in Prospecting and Drainage of Abandoned Mine Water

通过 对采 空区 积 水规 律的 分 析与 研究 ,提 出在 积 水采 空区 下 沿空 掘进 采 用煤 电钻 探 放水 技术 及 方法 ,解 决了钻 机探 放 水的 塌孔 问 题,既保 证了 沿 空掘 进的 安 全,又 取 得了 较大 的 经济 效益 。

Through analyses and studies on water ponding patterns in abandoned workings, put forward a suggestion of drainage technique and method during road driving along next goaf under a ponding goaf to use electric coal drill, solved caving problem during prospecting and drainage, not only ensuring safety during road driving along next goaf, but also acquiring major economic benefit.
