苏联煤矿广泛采用МК—97型组合式支架,到目前为止这种支架是0.7米厚煤层唯一批量生产的综采用的设备。1984年,15.6％的综采工作面配备1МК—97Д型支架,使用这些支架每年采煤2660万吨。 随着批量生产М—103型联动式支架,而这种支架也与1МК—97Д型支架一样用于回采相同厚度煤层时可实现机械化支护,从 The Soviet coal mines widely used МК-97-type composite bracket, so far this bracket is the only batch production of 0.7 m thick seam comprehensive utilization of equipment. In 1984, 15.6% of the fully mechanized coal mining face was equipped with 1МК-97Д-type stents, which use 26.6 million tons of coal per year. With the mass production of М-103-type linkage bracket, and this bracket and the same as 1МК-97Д-type support for mining the same thickness of the coal seam can be mechanized support, from
