采煤方法是煤矿生产工艺的中心。采用合理的采煤方法,是搞好矿井生产的关键,也是改善矿井各项技术经济指标的必然途径。 我省统配煤矿从1979年把改革老式采煤方法列为调整工作的一项重要内容以来,老法回采工作面的个数虽然逐年减少,产量比重逐年下降,但是由于采煤方法改革的范围小,由此所获得的技术经济效果并不明显。 Coal mining method is the center of coal production process. Adopting reasonable coal mining method is the key to improve well production and also the inevitable way to improve various technical and economic indicators of mine. Since the reform of the old-style coal mining method was listed as an important part of the adjustment work in 1979, the number of coal mining faces in the province decreased from one year to the next while the proportion of output declined year by year. However, due to the scope of the reform of coal mining methods Small, the technical and economic results obtained are not obvious.
