工作面瓦斯预抽效果检验是衡量措施效果的重要依据。通过对目前单一指标检验方法的分析,提出了残余瓦斯含量指标与无线电波透视技术和历史资料分析法相结合的多指标综合检验方法。利用该方法对中岭煤矿12013回采工作面的瓦斯预抽效果进行了检验。检验结果表明,多指标综合检验方法可以集单一指标之优势,避免单一指标法只能从走向上或倾向上给出检验结果的缺点,检验结果准确可靠,更加接近预抽效果实际。
Gas pre-pumping effect test is an important measure of the effectiveness of measures. Based on the analysis of the current single index test method, a multi-index comprehensive test method combining residual gas content index with radio wave perspective technology and historical data analysis method is proposed. This method was used to test the gas pre-pumping effect of 12013 working face in Zhongling Coal Mine. The test results show that the multi-index comprehensive test method can take advantage of a single index to avoid the single index method can only give the shortcoming of test results from the trend or tendency, the test results are accurate and reliable, and closer to the actual results of pre-pumping.
