摘要
较大型地质构造是影响煤矿高效生产的突出问题之一,而停采线附近的落差大于煤厚的断裂构造或大型岩溶陷落柱造成大范围顶帮破碎,对工作面末采期间的安全生产造成一定影响。本文以散射波成像技术对岩溶陷落柱开展震波场特征研究,并采用无线电坑透、专项探测钻孔施工对散射波探测成果进行进一步验证,有效圈定新景矿8128工作面停采线附近预测陷落柱的形态规模,指导工作面安全回采。
Large geological structure is one of the outstanding problems affecting the efficient production of coal mines.The fracture structure with a drop larger than the thickness of coal near the stop line or large karst collapse column causes a large-scale roof collapse,which has a certain impact on the safety production during the final mining of the working face.In this paper,the scattering wave imaging technology is used to study the seismic wave field characteristics of karst collapse column,and the results of scattering wave detection are further verified by radio penetration and special detection drilling,effectively delineating the shape and scale of collapse column near the stop line of 8128 working face in Xinjing Mine,and providing a guide for the safe mining of the working face.
