长期以来,天井掘进一直是矿山井巷工程中的薄弱环节,劳动条件差,机械化程度低。近些年来,国外研究和制造了几种机械化程度较高的掘进方法和掘进设备。除吊罐、爬罐和深孔凿岩外,全断面钻进法取得了显著进展,有逐步取代其它掘进法的趋势;但就目前而言,吊罐和爬罐仍然是应用最广和比较完善的两种掘进设备。 For a long time, the tunneling has always been the weak link in mine shaft engineering, with poor working conditions and low mechanization. In recent years, several kinds of mechanized excavation methods and driving equipment have been researched and manufactured abroad. In addition to hanging cans, climbing cans and deep-hole drilling, the full cross-section drilling has made significant progress, with the gradual replacement of other tunneling trends; but for now, hanging jib and climbing cans are still the most widely used and compared Perfect two kinds of driving equipment.
