摘　　要：为了提高近距离煤层群的瓦斯治理效果,实现近距离煤层群的联合瓦斯防治,通过对瓦斯抽采技术的优缺点进行层次化分析,综合评价某种瓦斯抽采技术的可用性,提出了效能、成本效益、安全性及可行性4个方面的评价指标来判断瓦斯抽采技术的优劣性,并层次化分析了各种抽采方案的适用性。结果表明:方案3在抽采过程中诱发事故的可能性较高,但是方案3具有人员设备投入成本较低,顺层钻孔有效进尺长,条带抽采效果更为显著的优点,同时可以有效解决矸石排放和矸石山堆积的问题。In order to improve the gas control effect of close range coal seam groups and achieve joint gas prevention and control of close range coal seam groups.By conducting a hierarchical analysis of the advantages and disadvantages of gas extraction technology,the usability of a certain gas extraction technology is comprehensively evaluated,and four evaluation indicators including efficiency,cost-effectiveness,safety,and feasibility are proposed to judge the superiority and inferiority of gas extraction technology.The applicability of various extraction schemes is also analyzed in a hierarchical manner.The results indicate that plan three has a higher possibility of inducing accidents during the extraction process,but it has the advantages of lower personnel and equipment investment costs,longer effective drilling depth along the layer,and more significant strip extraction effects.At the same time,it can effectively solve the problems of gangue discharge and gangue pile accumulation.
