地质构造复杂区域开采槽波物探技术探索与应用

白坪煤业公司21071工作面回采受北部箕F₈₇断层及白坪滑动构造叠加影响，煤层厚度变化较大，伴生构造发育，隐蔽致灾因素较多，严重威胁和制约工作面的安全生产。为防止瓦斯超限、误揭断层、煤层突变造成安全事故，通过对21071工作面三软煤层开展槽波探测技术试验，查明了煤层厚度变化及构造发育情况，为工作面超前灾害治理及顺利回采提供了地质依据，并验证了槽波物探技术探测效果及其在郑州矿区的适应性。

Exploration and application of groove wave geophysical exploration technology in mining area with complex geological structure

The stoping of the 21071 working face of Baiping Coal Industry Company is affected by the superposition of the Northern Ji F₈₇ fault and the sliding structure of Baiping，the thickness of the coal seam varies greatly，the associated structure develops，and there are many hidden disaster causing factors，which seriously threaten and restrict the safe production of the working face.In order to prevent safety accidents caused by gas overrun，fault uncovering by mistake and coal seam mutation，by carrying out in-seam wave detection technology test on the "Three Soft Coal Seams" of the 21071 working face，the thickness variation and structural development of the coal seam were found out，which provides geological basis for advanced disaster control and smooth stoping of the working face.The effect of in-seam wave geophysical technique and its adaptability in Zhengzhou mining area were also verified.
