摘　　要：随着煤炭的大量开采,浅层的煤炭资源越来越少,随着煤矿开采深度的增加,经常会钻遇坚硬岩层,现有硬岩钻进技术存在钻进效率低、粉尘无法解决等问题。为解决煤矿井下硬岩钻进现有问题,在新集矿区开展了适用于坚硬岩层的冲击回转钻进工艺研究,并进行工业性试验。试验表明,冲击回转钻进工艺有效地解决了煤矿井下硬岩钻进难题,与回转钻进工艺相比,钻进速度有较大提高。With the massive exploitation of coal,shallow coal resources are becoming less and less.As the depth of coal mining increases,hard rock formations are often encountered.The existing hard rock drilling technology has low drilling efficiency and dust cannot be solved.In order to solve the existing problems of hard rock drilling in coal mines,the research on impact rotary drilling technology for hard rock formations was carried out in the new mining area,and industrial tests were carried out.The test shows that the impact rotary drilling process effectively solves the problem of hard rock drilling in coal mines,and the drilling speed is greatly improved compared with the rotary drilling process.
