自移式液压支架是保证采煤机、工作面运输机充分发挥其能力,同时是使采煤工作面增加产量、提高效率、降低成本、减轻劳动强度和保证安全生产的有效设备。目前, 自移式液压支架已成为采煤综合机械化的关键设备之一。 鉴于缓倾斜薄煤层在四川省煤矿中所占 比重较大,为了适应煤炭工业发展的需要,加快缓倾斜薄煤层采煤综合机械化的步伐,一九七三年五月四川省科委、四川省煤管局作出进行“缓倾斜薄煤层液压支架研制”的决定。随后由重庆煤炭科学研究所、四川松藻 Self-moving hydraulic support is to ensure that shearer, face conveyors give full play to their ability, while increasing the production of coal mining face, improve efficiency, reduce costs, reduce labor intensity and ensure safe production of effective equipment. At present, self-moving hydraulic support has become one of the key equipment for comprehensive mechanization of coal mining. In view of the large proportion of gently inclined thin seam in the coal mines in Sichuan Province, in order to meet the needs of the development of the coal industry and speed up the pace of comprehensive mechanization of coal mining in gently inclined thin seam, in May 1973, Sichuan Provincial Science and Technology Commission, Sichuan Province The Coal Administration made the decision to “develop a hydraulic support for gently inclined thin seam”.
