随着我国综合机械化采煤的发展,液压支架数量日趋增多,由于支护强度、结构高度的增大,使支架总体越来越重,这就给支架的推广、使用及改善煤矿安全生产带来一定困难。因此,迫切要求液压支架由重型向轻型发展。本文依据实测资料,从矿压角度谈谈实现液压支架轻型化的必要性及其措施。 With the development of mechanized coal mining in our country, the number of hydraulic supports is increasing day by day. Due to the increase of support strength and structure height, the overall support is getting heavier and heavier, which gives the promotion and use of support and the improvement of safety in coal mines Must be difficult. Therefore, it is urgently required that the hydraulic support be developed from heavy-duty to light-duty. Based on the measured data, this paper discusses the necessity and measures to reduce the weight of the hydraulic support from the perspective of rock pressure.
