摘要
为了优化高突矿井地质异常体的探测效果,基于地震法和无线电坑透法,结合高突矿井瓦斯地质因素,采用以锤击激发为震源、以滚动式短排列探测为测量方式的便携地震法,结合高密度无线电坑透法实施重难点分区探测,提出了一种高效、精细的地质异常体综合探测技术。结果表明:采用此探测技术可探查采掘工作面内部及外围100 m范围内断层、裂隙等精细地质异常体的赋存状况,消除井下物探施工时放炮给高突矿井带来的安全隐患,全面完善工作面内部及外围煤岩层的地质构造分布信息,同时重难点分区对比探测提高物探效率,实现高突矿井地质异常体的高效、精细探测。
In order to optimize the detection effect of geological anomaly body in high outburst mine,based on seismic method and radio wave perspective technology,combined with gas geological factors of high outburst mine,the portable seismic method,which takes hammer excitation as the source and rolling short array detection as the measurement method,combined with the high-density radio wave perspective method,is used to carry out the differential detection of key and difficult areas.An efficient and precise comprehensive detection technique for geological anomalies is proposed.The results show that this technique can be used to detect the distribution of fine geological anomalies such as faults and fissures within 100 m of the working face and its periphery.It can eliminate the hidden danger brought by blasting construction of geophysical prospecting to the high outburst mine,and perfect the geological structure distribution information of the coal strata inside and around the working face.At the same time,the contrast detection of heavy and difficult areas can improve the efficiency of geophysical exploration and realize the efficient and fine detection of geological anomalies in high outburst mines.
