摘要
选择无线电波透视和音频电透视两种物探方法,对杭来湾煤矿地质状况进行探查。利用两种方法的不同功能,分别圈定了30202工作面内隐伏构造分布情况和顶板以上100 m范围内导含水性情况,进一步查明内部隐伏构造、导含水构造裂隙发育状况,判明作业面顶板砂岩裂隙水导水性,为编制回采前疏放水设计、冲刷构造异常区安全技术措施和回采过程安全生产提供地质资料和技术保障。通过回采过程中出水量和夹矸情况的验证,充分证明了综合物探方法在探查地质构造和煤层顶板富水性具有很高的准确度,值得大范围推广和使用。
Two physical prospecting methods, radio wave perspective detection and audio frequency electric perspective detection, were selected to explore the geological condition in Hanglaiwan Coal Mine. Based on their different functions, the distribution of hidden structures inside the 30202 working face and hydraulic conductivity within 100 m above the roof were determined respectively. Then, the study further identified the internal hidden structure and water-conducted fracture development and determined the water conductivity of roof sandstone fracture water of the working face, which could provide geological information and technical guarantee for compiling pre-mining drainage design, safety measures for scouring structural anomalies, and safe production in the mining process. The verification of water yield and gangue fully proved the high accuracy of the comprehensive geophysical prospecting method in the exploration of geological structures and the roof water-richness, which is worthy of widespread promotion.
