摘　　要：为提高煤矿瓦斯抽放效果,保证安全生产,根据某煤矿瓦斯抽放的实际条件,对钻场的钻孔数量与抽出量、钻孔预抽时间与抽放量关系进行统计分析与优化,得出了该煤矿每个钻场的钻孔数量应为30个左右、最佳抽放时间在18个月以内。该结果对提高煤矿瓦斯抽放效果具有一定的参考价值和指导意义。In order to improve the effect of gas drainage in mine, and to promote production safety. According to the actual conditions of gas drainage in some coal mine, the relations of the number of drilling holes with the extracts quantity, and the forepumping time with the drainage quantity are statistical analyzed and optimized at drilling fields. Giving the conclusions that the number of drilling holes are about thirty, and the optimum drainage time is within 18 months at each drilling fields in the mine.The results have certain reference value and directive significance to improve the effectiveness of gas drainage.
