摘要/Abstract

摘要： 针对矿山多层采空区钻探及测量的需要,提出采用贯通式潜孔锤反循环钻进技术穿越多层采空区的新方法,并研制了GQ-142贯通式潜孔锤。采用VB语言编写的贯通式潜孔锤模拟仿真电算程序对GQ-142贯通式潜孔锤的主要性能参数进行了仿真计算,可得:额定风压为18×10⁵ Pa、额定耗风量为14.86 m³/min、单次冲击能为413.07 J。与此同时,对GQ-142贯通式潜孔锤进行了多层采空区的钻进试验,结果表明:潜孔锤冲击碎岩效果明显,平均钻进效率达到13.08 m/h,并且与C-ALS三维激光扫描仪配套使用,成功实现两层采空区的钻探及测量。

Abstract: In order to resolve the problem of multilayer goaf drilling and measurement, a new method, which adopts reverse circulation drilling technology with hollow-through DTH air hammer to pass through multilayer goaf is proposed, and a GQ-142 hollow-through air hammer is developed. The main performance parameters of the GQ-142 hollow-through DTH air hammer are computed using the program of “hollow-through DTH air hammer computational simulation and analysis” which is written in VB language. Analysis results show that the rated air pressure is 18×105 Pa, the rated air consumption is 14.86 m3/min, and the single impact energy is 413.07 J. A field test using GQ-142 hollow-through DTH air hammer to pass through multilayer goaf is carried out. Testing results show that, using DTH air hammer, the impact effect of rock fragmentation is obvious and the average drilling efficiency is 13.08 m/h. Using the GQ-142 hollow-through DTH air hammer and C-ALS 3D laser scanner can successfully pass through and measure the two layers of goaf.

Key words: mine safety, multilayer goaf, hollow-through DTH air hammer, reverse circulation drilling, computational simulation, C-ALS 3D scanning
