联邦德国每年掘进巷道约500公里,总造价30亿西德马克。目前采用掘进机掘进的巷道比前20年大为增长。掘进机掘进效率高,速度快、经济效益好、安全可靠。掘进机的应用范围包括:全断面掘进机掘进岩石巷道,悬臂式掘进机(截割头掘进机)掘进煤层巷道(不含采区顺槽),悬臂式掘进机(冲击头掘进机)掘进采区顺槽。此外,许多煤矿仍用传统的钻眼爆破法掘进巷道,钻爆法在一定情况下仍是必须使用的。
Federal Republic of Germany each year driving about 500 km roadway, the total cost of 3 billion mark. At present, the roadway boring with roadheader has greatly increased compared with the previous two decades. Roadheader driving efficiency, fast, good economic returns, safe and reliable. Tunnel boring machine applications include: full-face boring machine tunneling rock roadway, cantilever boring machine (cutting head boring machine) heading coal roadway (excluding mining area along the groove), cantilever boring machine (impact head boring machine) mining District Shun slot. In addition, many coal mines still use traditional drilling and blasting methods to excavate roadways, and the drilling and blasting method must still be used under certain conditions.
