摘要
针对建庄煤矿三盘区回采工作面煤层厚度变化较大,瓦斯涌出量变化较大的情况,矿井采取了有针对性的瓦斯治理措施,即综放工作面精准的分段瓦斯抽采方案,不仅有效解决了上隅角瓦斯异常涌出的问题,同时也保证了回采工作面安全高效的生产。
Aiming at the situation that the thickness of the coal seam in the mining face of the third panel of Jianzhuang Coal Mine changes greatly and the amount of gas emission changes greatly, targeted gas control measures were taken, that is, the accurate subsection gas drainage scheme in the fully mechanized caving face, which effectively solved the problem of abnormal gas emission in the upper corner and ensured the safe and efficient production of the mining face.
