煤岩层裂隙填充物性质预测研究
|
摘要
利用Schoenberg线性滑移裂隙介质理论的特定情况和含裂隙煤层波场数值模拟结论,计算出三维三分量(3D3C)地震勘探中的纵波和转换横波速度比,并利用3D3C技术对钱家营煤矿煤岩层裂隙中的瓦斯和水患进行了预测研究,经井下验证,效果较好。为今后煤矿瓦斯和水患的综合治理,提供了一个有效手段。
Based on the specific condition of the Schoenberg's theory of linear slippage in fractured media and the wave field numerical simulative conclusion of cracked coal beds,the ratio between the velocity of the P-wave and that of the P-SV converted wave in three-dimensional three-component(3D3C) seismic exploration is calculated, and the gas and water in the cracked coal bed of Qianjiaying Coal Mine is researched and predicted. The prediction result is proved by mining practice. The 3D3C seismic exploration technology provides an effective means for comprehensive treatment of gas and water in coal mines.
