我矿推广使用平巷掘进机械化作业线是从1973年河北铜矿会议以后开始的。几年来我们发动和依靠群众,自力更生,制造了机械化新设备38台,其中有PYT-2型凿岩台车15台、CGJ-2Y凿岩台车1台、斗式转载车11台、风动和液压梭车各2台、顶耙武装岩机1台、液压凿岩机6台;此外还制造了1米~3侧卸式方形矿车96辆,与斗车配套的V形矿车26辆,装备了4条平巷掘进机械化作业线,和1条全液压科研线。从1974年至
I mine to promote the use of roadway mechanized tunneling operation is from the Hebei Copper Mine Conference in 1973 after the start. Over the past few years, we mobilized and relied on the masses to make our own efforts and created 38 new mechanized equipment, including 15 PYT-2 rock drilling rigs, 1 CGJ-2Y rock drilling rig, 11 bucket-carrying vehicles, And hydraulic shuttle each 2 sets, top rake armed rock machine 1, 6 sets of hydraulic rock drill; In addition, also produced 1 m ~ 3 side unloading square barrels of 96 cars and Bucket matching V-shaped tub 26, Equipped with 4 lane driving mechanized operation line, and a full hydraulic research line. From 1974 to
