超前钻探预测预报技术在煤矿中的应用

Application of Advanced Drilling Prediction Technology in Coal Mine

基于裕兴煤矿采掘区域内小褶曲发育、煤层赋存不稳定等异常情况以及隐伏断层、陷落柱、空腔陷落柱等地质构造对煤矿安全生产造成的瓦斯、水害威胁,为了进一步了解采掘巷道地质构造情况,保证巷道安全快速掘进,二采区北翼辅运巷在掘进过程中决定采用超前钻探技术手段进行地质构造预测预报,明确了巷道开口前方33 m处存在一个空腔陷落柱,为巷道安全掘进奠定了基础。

Based on the development of small folds, instability of coal seam and other abnormal conditions in the mining area of Yuxing coal mine, as well as the gas and water hazards caused by geological structures such as hidden faults, subsided columns and cavity collapse columns, in order to further understand the geological structure of the excavation roadway and ensure the safe and rapid excavation of the roadway, in the process of driving,advanced drilling technology to predict the geological structure was adopted in the auxiliary haulage roadway in the north wing of the second mining area. It was clear that there was a cavity collapse column 33 m ahead of the opening of the roadway, which laid a foundation for the safe driving of the roadway。
