    Gas-geological Rules Analysis and Control Technology at Working Face in Serious Outburst Coal Seams

    • 摘要: 以瓦斯地质理论为基础,对严重突出煤层回采工作面的瓦斯规律及控制技术进行了分析研究。在根据现场资料分析矿井瓦斯地质规律和突出规律的基础上,从采区及工作面瓦斯地质规律、工作面瓦斯赋存模型、工作面区段突出危险性等方面对工作面瓦斯地质规律进行了分析,并利用工作面瓦斯地质动态分析及管理系统,对工作面进行瓦斯地质信息的动态管理和防突工作的全过程控制,绘制了渐变图式工作面地质图。现场应用表明,工作面瓦斯地质规律分析及控制技术使工作面防突措施更有针对性,能减少防突工程量,提高工作面施工效率。

       

      Abstract: Based on gas-geology theory, the gas-geology laws and control technology at working face in serious outburst coal seams were analyzed. On the basis of the analysis of coal mine gas-geological laws and outburst laws according to the in-situ data, the work face gas-geological laws was analyzed from mining area and working face gas-geology laws, work face gas occurrence model and outburst dangerous section and other aspects. The working face gas-geology dynamic analysis and management system is used to monitor the gas-geology information dynamic management and the whole process in outburst prevention at working face, and the gradient schema geological map at working face have drawn. Field application shows that the technology of working face gas-geological laws analysis and its control makes the outburst prevention measures more targeted, which can reduce quantity of outburst prevention and improve the working efficiency of working face.
