摘要
以马兰矿12513Ⅱ工作面为研究对象,通过数值模拟分析了最优钻孔参数,并与马兰矿实际地质条件结合,在马兰矿采用本煤层顺层钻孔、低位裂隙带钻孔、低位高抽巷抽采和上隅角悬管抽采的防治措施进行瓦斯防治,并采用钻孔取样的方式进行效果检验,取得了良好的防治效果。
Taking the 12513 II working face of Ma Lan mine as the research object, through numerical simulation analysis of the optimum drilling parameters and combining with the actual geological conditions of Ma Lan mine, the prevention and treatment measures for the prevention and treatment of the coal seam in the coal seam, the low level fissure zone drilling, the low level high pumping roadway extraction and the upper corner hanging pipe extraction are used in the Ma Lan mine, and the drilling is adopted. The way of sampling is tested, and good control effect is achieved.
