摘要
为了对煤矿巷道掘进前方各类含水体进行有效的预测预防,消除突水的潜在威胁,保证煤矿的安全掘进,文章以矿井瞬变电磁法和矿井直流电法探测技术为例,通过井下超前探测数据采集、数据预处理和反演计算,形成电阻率剖面图,来解释巷道掘进头前方含水情况,建立了一套适合煤矿掘进过程中超前预报含水体的技术方法,结果表明:综合采用矿井瞬变电磁法和矿井直流电法对各类含水体探测更为精细。
In order to effectively predict and prevent each type water bearing body in a front of the heading face of the mine roadway, to eliminate the potential danger of the water inrush and to ensure the safety heading of the mine, base on the mine transient electromagnetic method and the mien DC method detection technology as examples, the data collection, data pretreatment and inverse calculation of the advance diction in the underground mine were applied to form a cross section of the resistivity to explain the water bearing conditions in the front of the heading face of the mine roadway. A set suitable technical method to predict water bearing body during the mine roadway heading process was established. The results showed that the combined application of the mine transient electromagnetic method and the mine DC method could make the detection of each type water bearing body more accurately.
