New Technique of Gas Drainage by Long Horizontal Roof Rock Hole

采用顶板岩层水平长钻孔抽放邻近层和采空区瓦斯是一项新技术 ,全面介绍了该技术研究的最新进展。研究中综合运用了矿山压力和岩层移动理论、有限元数值分析方法、瓦斯越流理论以及试验研究的方法。这一新技术的研究填补了国内空白 ,该成果对高产高瓦斯工作面的瓦斯治理具有普遍的指导意义。

Applying long horizontal roof rock hole to drain the gas from adjacent seam and goaf is a new technique.In this paper,introduces the latest progress of this technique is introduced fully.The principle about rock pressure and strata movement,finite element method,the principle of gas leak and experiment method study is applied in study.The study about this new technique fills the blank of our nation.This new technique has wide instructional significance for gas-control in coal face of high-production and high-gas.
