一 水平分层采煤方法的概述我国与苏联均是拥有急倾斜煤层的国家。急倾斜煤层的埋藏量(A+B+C_1级)在我国据1956.1.1的统计数字,占全国总埋藏量的4.5%;其中薄煤层占1.6%,中厚煤层占1.7%,厚煤层占1.2%。苏联的顿巴斯和库兹巴斯均埋藏有大量的急倾斜煤层,在顿巴斯主要是薄煤层群;在库兹巴斯则有各种厚度的煤层。

Outline of a Horizontal Stratified Coal Mining Method Both China and the Soviet Union are countries with steep coal seams. According to the statistics of 1956.1.1 in our country, the burial amount of steep coal seam (A + B + C_1 grade) accounts for 4.5% of the total national burial volume; the thin coal seam accounts for 1.6%, the middle and thick seam accounts for 1.7%, the thick seam 1.2%. There are a large number of steep coal seams buried in the Soviet Union, both in Donbass and in Kuzbass, mainly in thin coal seams in Donbass and coal seams of various thicknesses in Kuzbass.
