摘要
针对煤矿硬岩钻进效率低、粉尘浓度大等问题,设计了一种利用高压水驱动的冲击钻具,可实现冲击+回转钻进工艺,提高煤矿井下硬岩钻进效率,避免粉尘污染。对设计方案进行了分析,阐述了工作过程,并对其主要参数进行了设计计算,对高压水锤关键技术问题进行了探讨。对高压水锤的设计和研究具有一定参考意义。
For hard rock drilling as low drilling efficiency, high dust concentration problems, designed a high pressure water powered hammer, it can realize the impact ＋ rotary drilling process, improve coal mine hard rock drilling efficiency, avoid dust pollution. In this paper, has analyzed its design scheme, described its work processes, and design calculation of its main parameters, discussed the key technical issues. It has some certain reference value for high pressure water powered hammer design and research.
