摘要
在煤矿巷道掘进过程中会遇到复杂多变的地质构造,利用超前探测技术探测煤层中的地质构造,以保证煤矿安全生产,在板集煤矿采用了DTC-150超前探测系统。结合后期实际揭露的地质情况综合分析,验证了该系统在煤矿生产中地质预报的精准性,探测出回风巷掘进工作面前方煤层破碎带与断层。
Complex and changeable geological structures will be encountered in the process of coal mine roadway excavation.The advanced detection technology is used to detect the geological structure in the coal seam to ensure the safe production of coal mine.DTC-150 advanced detection system is adopted in Banji Coal Mine.Combined with the comprehensive analysis of the geological conditions actually exposed in the later stage,the accuracy of the geological prediction of the system in coal mine production is verified,and the coal seam fracture zone and fault in front of the heading face of return air roadway are detected.
