陷落柱导富水性综合探测技术

陷落柱在华北煤田广泛发育和分布,为避免井下采掘中揭露陷落柱造成水害事故,以葛亭煤矿为例,在对比研究了各种物探方法应用条件的基础上,根据EH4法的电性场分析和SYT法的相对地应力分布情况,对葛亭煤矿已有或可能存在的陷落柱进行综合探查。对探查数据进行精细解释,及陷落柱的导富水性进行综合评判,结果表明,两种方法的对比探测对于寻找陷落柱位置和确定富水范围非常有效,能为陷落柱导富水性的探测提供可靠依据。

Comprehensive Survey Technology of Sink Hole Water Yield Property and Conductive

The sink hole was widely developed and distributed in Huabei Coalfield, in order to avoid the wa-ter disaster occurred with the sink holes opened in the underground mine, through the comparing research onthe application of every kinds of geophysical prospecting on the Geting Coal Mine, there was a comprehen-sive survey of potential sink hole in Geting Coal Mine, with the electric - field properties analysis of EH4and the relative crustal stress distribution of SYT. By explaining the exploration data carefully and judgingthe sink hole water yield property and conductive comprehensively, it shows that the two methods of detectionachievements is consistent through comparison and validation. It is very effective to seek the sink hole posi-tion and determine water - enriched extent through the contrast of the two prospecting methods. It also pro-vides a reliable basis for detecting sink hole water yield property and conductive.
