摘要
以山西焦煤集团晋中某矿采矿地质条件为研究背景,综合考虑该区域的特殊煤层地质条件,分别针对该区域矿井高瓦斯、低透气性、煤层自然发火严重、水文地质条件复杂等因素进行分析研究,确定采用近距离保护层开采技术作为该矿井的有效防突手段,并对开采作业方式、工作面通风和瓦斯抽采提出了实施方案。该研究成果为该矿区实行保护层防突技术提供了合理的理论验证和技术支撑。
A coal mine in Jinzhong is as the research background. Comprehensive considering the special geological conditions,analyzes the elements such as high gas,low permeability,serious spontaneous combustion,complex hydrogeology condition. The technique of protection layer mining in short distance is adopted to as the effective outburst prevention measure. Then the implementation plans of mining operation mode,working face ventilation and gas drainage are put forward. The research results provide reasonable theoretical test and technical support for similar coal mine to use outburst prevention technique of protective layer to removing outburst.
