摘要
为了准确、快速地预测煤与瓦斯突出,以焦作中马村矿为实施矿井,采用瓦斯地质理论全面分析了影响瓦斯突出的地质条件,利用数量化理论Ⅲ筛选了瓦斯突出的敏感指标,应用数量化理论Ⅱ建立了煤与瓦斯突出区域性预测的综合判据,选用二维判别方法对中马村矿二1煤层未采区进行了预测,预测结果为突出危险区23个,突出威胁区41个,非突出区106个,与实际突出结果吻合.表明采用瓦斯地质理论和数量化理论相结合的方法预测煤与瓦斯突出是可行的.煤与瓦斯突出区域性预测综合判据的建立使突出预测规范化,有望推广应用.
In order to predict coal and gas outburst accurately and rapidly, geological conditions were analyzed by gasgeology theory, sensitive factors were screened by the third theory of quantification, comprehensive criteria was set up by the second theory of quantification. Zhongmacun Mine was predicted by two dimensional discrimination, prediction results: outburst dangerous area is 23, outburst threatening area is 41, no outburst area is 106, and it is identical with the practical results. The research indicated that it is better to predict coal and gas outburst by both gasgeology theory and the theory of quantification Comprehensive criteria can make prediction of outburst normatively and be applied widely.
