支架工作是采矿作业中的一个主要环节,而且是一个体力劳动最繁重与难于进行机械化的操作过程。它的成本占主要巷道的25～30%或更多,占采矿的10～25%。改进支架工作来降低成本与减轻体力劳动,是目前采矿工作者的迫切任务。采矿科学技术发展趋向指出:矿山支架工作,一方面走向采用金属支架,而另
Stent work is a major part of the mining operation, and is one of the most labor-intensive and difficult to mechanize operations. Its cost accounts for 25-30% or more of the main roadway and 10-25% of mining. To improve the work of stents to reduce costs and reduce physical labor is an urgent task for mining workers. Mining science and technology trends pointed out: mine support work, on the one hand toward the use of metal brackets, while the other
