Abstract:
Under the condition of short distance outburst coal seams group, carrying on the effective regional gas control measures, including the necessary gas extraction and coal seam outburst elimination, can ensure safety in the process of mining. In response to the problems of the district gas control of short distance outburst coal seams group in Yuanxiang coal mine, based on the target coal seams gas storage and transportation analysis, the paper puts forward the suitable for Yuanxiang coal mine continuous mining district gas outburst control measures, Optimizes the original coal seam gas extract parameters and the protected coal seams in pressure relief gas extraction parameters, and forms the Yuanxiang coal mine district comprehensive gas control technology. The usage of the technique can effectively reduce the gas content of outburst coal seams, eliminate the outburst risk of outburst coal seams, ensure the effectiveness and continuous of coal mining, and provide the technical guarantee for the safety and high quality of mining operations.
