摘　　要：针对马兰矿在煤与瓦斯突出危险区巷道掘进时面临邻近层消突的现状,选择在8号煤层掘进过程中对9号煤层进行联合消突方案的研究与应用。实践表明:采用联合消突的方式,不仅缩短了工作面执行综合区域防突措施的时间,确保了“抽、掘、采”平衡,同时,在进行巷道掘进时,能够降低掘进区域突出危险性,保证矿井安全生产,减少瓦斯治理费用,创造更大的社会和经济效益。Aiming at the present situation that Malan Coal Mine was facing extinguishing outburst in adjacent seam when tunneling in dangerous area of coal and gas outburst,the study and application of joint extinguishing outburst scheme for No.9 coal seam in No.8 coal seam tunneling process were selected.Practice showed that the method of joint outburst elimination not only shortened the time of implementing comprehensive regional outburst prevention measures in working face and ensured the balance of"pumping,excavating and mining",but also reduced the risk of outburst in driving area,guaranteed the safety of mine production,and reduced the cost of gas control,and created greater social and economic benefits.
