Abstract : In order to improve the drilling efficiency in hard stratum in coal mines and solve the technical problem of borehole drilling in hard stratum, Model ZYW4000G highspeed drilling machine was developed, which has the features of high drlling speed, large output torque, strong drilling ability and so on. This paper described the overall structure of this drilling machine and its key technologies, including the doublemotor power head driving system, the hydraulic system and the adjusting system for the drilling posture. The drilling tests both in the hard stratum and coal seam indicated that this drilling machine was rational in structure and easy to operale and had a litle heating. When this drlling machine is used with the relevant dilling tools to drill holes in the hard stratum and coal seam, its drlling efficiency is much higher than that of the ordinary drilling machines.

在煤层中钻孔泄压,是矿井瓦斯治理最有效的手段之一,而钻机是煤矿生产中不可或缺的设备。在煤矿钻探时,不可避免地要遇到坚硬岩层,现有的钻孔设备及施工工艺无法有效且便捷地在坚硬岩层中钻孔,施工效率极低。如何提高在坚硬岩层中钻孔施工效率,是一个驱待解决的难题。
坚硬岩层快速钻进工艺的基本思路是通过高硬度回转钻具或冲击回转钻具配合高速切削,来提高钻孔施工的效率()。其基本方法是采用潜孔锤+全

面钻头配合钻机高速切削,或采用金刚石取芯钻进配合钻机高速切削。该工艺方法要求钻机最大转速能达到300~500r/min,且具有足够的切削力矩。现有的煤矿钻机,如ZYW系列钻机、ZK系列钻机及 ZY系列钻机,其功率小、转速低、输出转矩小,不能完全胜任该施工工艺[2-4]。因此,研发应用能进行高速切削的高转速钻机势在必行。
在此,笔者着重介绍ZYW-4000G高转速钻机的主要结构、关键技术及其在坚硬岩层、顺煤层钻孔中的试验情况。
