摘要
通过对保护层开采引起瓦斯压力、煤层瓦斯含量、煤层变形、钻孔瓦斯涌出量等参数变化的考察和分析,能够掌握保护层开采的保护范围与效果,并根据此研究结论,制定措施,以指导安全生产。
According to the observalion and analysis on the change of parameters caused by protecting layer mining,including gas pressure,the content of gas which belongs to coal seam,the change of coal seam,the gushing amount of gas which is from drilling hole,and so on,we can grasp the protecting scope and result of protection layer mining,and take measures on the basis of the research′s result so as to guide safe production.
