小煤柱综采放顶煤工作面瓦期涌出分析及治理

Analysis and Administration of Fire-damp Gush into Small Coal Column Combined Mining Top Blasting Face

针对小煤柱开采时相邻已采工作面采空区的瓦斯涌入本工作面,造成工作面瓦斯涌出量增大,工作面上隅角瓦斯浓度高,影响工作面安全生产的情况,对小煤柱综放工作面瓦斯涌出情况进行了测定、分析,并针对性地提出了相应的瓦斯治理方案,取得了明显的效果。

Being directed against the fire-damp gushed out form neighbour goaf into small coal column combined mining top blasting face, the high concentration of fire-damp influences the safety production of the face. The fire-damp gushed out in the small coal column fully-mechanized mine face has been determined and analyzed and puts forward the correspondent administration plan, which has got obvious results.
