突出煤层掘进工作面遇地质构造防突工程技术实践

Technical Practice of Preventing Outburst of Geological Structure in Excavation Face of Outburst Coal Seam

本文以山西新景矿煤业有限责任公司芦南二区3215辅助进风巷遇地质构造为例,阐述了突出煤层掘进工作面遇地质构造时采用的防治煤与瓦斯突出的相关工程技术措施,通过施工掌头地质探测孔、底抽巷区域预抽、帮孔区域造穴增透预抽、返头地质探测孔等综合防突措施,消除突出区域范围(评价范围)内的突出危险性,确保安全生产。

Taking the 3215 auxiliary air entry alley in the two district of Lunan, Shanxi Xinjing Coal Industry Co., Ltd. meeting with geological structure as an example, this paper expounds the related engineering technology of the prevention and control of coal and gas outburst in coal heading face meeting with geological structure. By means of such comprehensive outburst prevention measures as the construction of geological exploration hole, bottom of pumping drainage lane area, side anti-reflection drainage hole area, returned head of geological exploration hole highlight area （evaluation） in the outburst dangerousness will be eliminated, to ensure safety in production.
