| 摘 要： | 通过对盘江矿区老屋基矿121217工作面高位钻孔分析研究,不断优化高位钻孔参数,得出了高位钻孔各项参数的优化公式。利用该公式优化高位钻孔参数后可以准确确定高位钻孔最佳层位,提高抽放效果,降低瓦斯涌出量,为盘江矿区深部开采时的瓦斯治理探索出一条新途径。 |
| 关 键 词： | 高位钻孔 瓦斯抽放 参数优化 抽放浓度 |

| Abstract: | According to the analysis of Panjiang Laowuji Mine 121217 working faces high drilling,the essay continuously optimizes the high drilling parameters,and obtaine drilling parameters in the optimization formula.Using the formula can be high accurately determine the high position gas drilling's best horizon,improve the drainage effect,reduce gas emission,and explore a new way of deep mining Panjiang gas control. |
| Keywords: | high drilling gas drainage parameter optimization drainage density |
