随着我国采煤机械化程度的不断提高,厚煤层一次采全高的大采高技术不断推广,我县地方煤矿成功采用一次采全高开采技术,有效避免大量丢煤而影响煤炭采出率的现象。文章结合矿井实例,进一步论述了中厚煤层一次采全高技术在地方煤矿开采中的成功应用。 With the continuous improvement of mechanization of coal mining in our country, the technology of large-scaled mining with full height at a time has been popularized in our country. Local coal mines in our county have successfully adopted one full-height mining technology to effectively avoid the phenomenon of large amount of coal being thrown out and affecting the coal recovery rate. Combined with the mine example, the article further discusses the successful application of once mining full height technology of middle and thick coal seam mining in local coal mines.
