摘要
分析了顶板全程同步钻孔采空区瓦斯抽采技术的可行性,并用UDEC进行数值模拟确定了关键技术参数,为采空区瓦斯抽采提供了安全高效的技术手段,对综采工作面瓦斯治理具有重要意义。
The paper analyzes the feasibility of the gas extraction technology with roof full-range synchronization drilling in mined-out areas. Key parameters are determined by numerical simulation with UDEC, which offers safe and efficient technology for the gas extraction in the mined-out areas and is significant for the gas control in fully-mechanized mining face.
