反井钻机反井施工在柳州市1013人防工程竖井中的应用

摘要

反井钻机因其成孔质量高，施工速度快，已在各种暗立井、竖井、煤矿的反井、井下煤仓、溜煤眼、溜矸井、通风孔等工程中得到广泛应用。结合柳州市1013人防竖井工程，介绍了反井钻工艺原理、施工方法、钻掘精度控制、在不良地质层钻进技术及常见问题解决方法。%Hole drill hole because of its high quality, construction speed is fast, has worked in the dark shaft, shaft, well of coal mine, downhole coal bunker, coal slip eyes, slipped bottles well, vents, etc, is widely used in engineering. According to my company Liuzhou 1013 air-defense shaft engineering construction, introduces the well drilling technology principle, construction method, accuracy control, drilling and digging in the bad geological layer drilling technology and common problem solving methods.
