煤矿液压支架的现状与发展思路

Mine Hydraulic Support the Status Quo and Development Ideas

针对矿井条件不同,对液压支架提出不同要求。条件好的大型高产高效矿井,重点发展大工作阻力、高可靠性电液控制液压支架;条件复杂的矿井,重点发展适应难采煤层的各种支架,大批中小矿井将进行技术改造,推广使用紧凑型的液压支架。

Mine the different conditions on dttterent hydraulic support requirements.Good conditions for larg-scale high - yield and high efficiency mines, the work focused on the development of resistance, high reli- ability, electro - hydraulic control hydraulic support, conditions of the mine complex, and difficult to adapt to focus on the development of the various mining stent, a large number of small and medium - sized mines will carry out technological transformation, promote the use of to the compact hydraulic support.
