槽波探测技术在晋城矿区3~#煤层的应用与思考

Application and thought of slot wave detection technology in No.3 coal seam of Jincheng mining area

槽波探测技术主要是用来探测煤矿回采工作面内部地质构造分布、大小、形态以及煤层变化状态。通过分析近几年槽波探测技术在晋城矿区多个矿井的应用效果,结合理论分析和观测系统优化,总结得出:槽波在晋城矿区3#煤层的发育明显,但反演结果与实际情况还有差距;槽波探测的优势是确定煤层应力集中区和煤层变化带,对断层、陷落柱分辨能力有限。

Slot wave detection technology was mainly used in detecting the distribution, size, form of geological structure in mining face and the coal seam change state. By analyzing the application effects of slot wave detection technology in several mines at Jincheng mining area in recent years, combining with theoretical analysis and observation system optimization, it concluded that the slot wave developed obviously in No. 3 coal seam of Jincheng mining area, but the inversion results still had some differences with the actual situation; the solt wave detection had an advantage in determining the stress concentration zone and change zone of coal seam, but had limited capacity in analyzing the fault and collapse column.
