震波技术在高瓦斯突出矿井中的应用

Application of Seismic Wave Technology to High Gassy and Outburst Mine

为了及时准确地探测工作面前方及四周的地质情况,利用震波技术对高瓦斯突出矿井采掘工作面进行超前探测。根据震波在煤、岩体中传播时遇到不同界面发生反射这一原理,通过接收反射波信息,解析得到反射界面的距离,进而确定煤、岩体的形态及地质构造相对大小,以预报前方地质特征。此探测技术在平顶山十三矿的应用结果证明,该技术能够解决高瓦斯突出矿井地质超前探测方面的问题,节约了钻探成本,取得良好收益。

In order to on time and correctly explore the geological conditions at the front and around of the excavation face, the seismic wave technology was applied to the pilot prediction of the excavation and face and mining face in the high gassy outburst mine. According to the principle that the seismic wave would have different reflections when the seismic wave transmitted through different surface of the coal and rock masses, with the reflection wave information received, the distance of the reflection surface was analyzed and resolved. Therefore the shape of the coal and rock masses and the relative size of the geological structure could be determined and the front geolog- ical features could be predicted. The exploration technology was applied to the No. 13 Mine of Pingdingshan Coal Mining Group. The re- sults showed that the geological pilot exploration issue could be resolved in the high gassy outburst mine and the drilling and exploration costs could be reduced with good benefits.
