我国煤矿自1975年开始试验应用倾斜长壁采煤法以来,现在已推广应用到20多个矿区。目前,全国重点煤矿中约有13％的矿井采用倾斜长壁采煤法,其产量在统配总公司总产量中所占比例,以平均每年0.5％左右的速度递增。1988年统配煤矿使用该采煤方法的产量占总产量的5.73％。据对近十年新设计的23对大、中型矿井的不完全统计,采用倾斜长壁开采的矿井占52.17％。由此不难看出,倾斜长壁采煤法,在我国煤矿中的应用规模正在不断扩大。
Since 1975, China’s coal mines have been experimentally applied to tilt longwall coal mining methods and are now being widely applied to more than 20 mines. At present, about 13% of the key coal mines in the country adopt the inclined longwall coal mining method, and the proportion of its output in the total output of the headquarter is increasing at an average annual rate of about 0.5%. In 1988, the coal production by the coal mines accounted for 5.73% of the total output. According to the incomplete statistics of 23 pairs of large and medium-sized mines newly designed in the past decade, 52.17% of the mines are inclined and longwall mined. It is not difficult to see that the inclined longwall mining method, the scale of application in China’s coal mines are constantly expanding.
