摘要
Abstract
Daning Coal Mine 304 working face of No. 3 coal seam is in outburst danger zone, the method of pre-pumping coal seam gas using the bedding drilling was used in the regional outburst prevention management, the reasonable drilling ifeld number and borehole spacing parameters were determined. Tests the effect with the division of the regional evaluation unit, the test results show that: after pre-pumping coal seam gas ,the maximum residual gas content value is 6.43m3/t, the maximum solutions gas desorption quantity is 3.84m3/t, is less than 8m3/T. The working face gas drainage effect is up to the standard, which successfully eliminated the working face coal outburst danger.关键词
