某矿MLQ1-80型采煤机改造及井下实践分析

An Analysis of the Reform and the Practice of MLQ1-80 Coal-mining Machine

MLQ1-80型采煤机在中厚煤层中使用时,必须使机组上下往返一次才能完成一刀采完全高,某矿自制了1600×600的大滚筒装在MLQ1-80型采煤机组上,取代原800×600滚筒,实现了一次一刀采完全高。对此改造及实践作分析和总结,为采煤生产率的提高及该机的扩展应用进行了有益的探索。

From the analysis and conclusion on the reform and practice of MLQ1-80 coal-mining machine used in medium-thick coal seam, 1?600×600-diameter roller is made and installed in MLQ1-80 coal-mining machine. A useful exploration in the enhancement of coal-mining productivity and an extensive implication of the machine is done.
