【Abstract】 There are three coal-bearing beds in the Longtan coal-bearing series.The minable coal thickness varies between 0 and 6.8 m.The stability is very bad.The major factor affecting the variation of coal thickness is sedimentary formation,mainly characterized by the wave synsedimentary base,unample sediments supply,short stable coal-forming age,coal bed splitting and thin out as well as the syn-and post-sedimentary wash.Another important factor is post-tectonic and magmatic activities,such as compression by overthrust movement which makes the coal bed deformed into various shapes.更多还原
