针对煤层透气性差、抽采效果不理想的问题，赵庄矿应用了底板岩巷穿层钻孔预抽措施。通过对底抽巷的层位选择、穿层钻孔的布置、封孔工艺等影响瓦斯抽采效果的各个环节的分析研究，验证了采用底抽巷实施穿层钻孔预抽煤巷条带煤层瓦斯掩护巷道掘进的可行性和良好的瓦斯治理效果，为矿井的长远发展提供了安全保障。
針對煤層透氣性差、抽採效果不理想的問題，趙莊礦應用瞭底闆巖巷穿層鑽孔預抽措施。通過對底抽巷的層位選擇、穿層鑽孔的佈置、封孔工藝等影響瓦斯抽採效果的各箇環節的分析研究，驗證瞭採用底抽巷實施穿層鑽孔預抽煤巷條帶煤層瓦斯掩護巷道掘進的可行性和良好的瓦斯治理效果，為礦井的長遠髮展提供瞭安全保障。

According to the coal seam permeability difference and the not -ideal drainage effect, pre -drainage based an drilling through the floor roadway is used in Zhaozhuang Mine.analysis and study of the effecs gas drainage,including the bottom layer selec-tion, borehole layout and hole sealing technology,confirmed the feasibility and good gas treatment effect of this measure, which provi-ding security for the long-term development of the coal mine.
