摘要
为了提高超前探测的准确性,确保在小窑破坏区巷道掘进的安全,采用“物探现行,钻探验证”的物探和钻探相结合的综合超前探测技术,通过在红会一矿运用矿井震波超前探测技术(MSP)与长短钻验证相结合的方法探测小窑破坏区,本年度1701工作面少掘钻场7个,少打探孔49个,减少探孔进尺4165 m,取得了良好的社会经济效益。
In order to improve the accuracy of the advanced detection and ensure the safety of roadway excavation in the small coal mine damaged area,the comprehensive advanced detection technology combining geophysical exploration and drilling was adopted.In the No.1701 working face of Honghui No.1 coal mine,by using the mine seismic prediction(MSP)and long-short drilling verification method to detect the small coal mine damaged area,the number of drilling fields was reduced by 7,the number of exploration holes was reduced by 49,and the footage of exploration holes was reduced by 4165 m,and good social and economic benefits were obtained.
