苏联国内各矿区试用各种类型的加强和支撑式支架的大量研究工作证实了重复利用准备回采巷道的采煤工艺有广扩的前景。其主要内容之一是改善目前机械化采煤和人力支护、维修巷道的不相称状况。 莫斯科近郊煤炭科学研究所研制一种专门的巷道支护机组,利用它可以解决三个急待解决的课题:即保证回采后在矿压显现区内巷道维护效果;主要支护作业机械化;提高支护工作的安全性。 巷道维护机组由液压支架、支架安装装置及液压设备组成。
Extensive research trials of various types of reinforced and supported stents at various mines in the Soviet Union have confirmed the prospect of a widening of the coal mining process for the recovery of the roadway. One of its main contents is to improve the disproportionate situation of mechanized coal mining and manpower support and roadway maintenance. Coal Institute of Moscow suburbs to develop a special roadway support unit, which can be used to solve three urgent problems: to ensure that after mining in the mine pressure show area of roadway maintenance effect; mechanization of the main support operations; improve the support Protect the safety of work. Roadway maintenance unit consists of hydraulic support, bracket mounting device and hydraulic equipment.
