| 摘 要： | 煤层瓦斯压力测定是煤矿瓦斯防治基础参数测试内容之一,其最理想的测定条件是穿岩钻孔测压,但当前多数矿井因主要巷道均布置在煤层中而不得不采用煤层钻孔测压。目前本煤层瓦斯压力测定由于封孔难度大,传统的封孔工艺不能适用煤层封孔的需求,测压成功率较低。因此提出了黄泥-聚氨酯快速封孔方法,并在九里山矿进行了现场实验,取得了较好的效果。

| Abstract: | Coal seam gas pressure measurement is one of the basic parameters on gas control in coal mine.The ideal measurement condition is drilling manometry through rock,but the majority of the mine had to use coal seam drilling manometry due to the major roadway arranged in coal seam.Currently,the traditional sealing can not be applied to the demand of coal seam sealing because of the sealing difficulty in mining-coal bed gas pressure measurement.Therefore,yellow mud-polyurethan fast sealing method was proposed,and field experiments in Jiulishan coal mine were done,which achieved good effect. |
