兖州矿务局主要可采煤层有3、16、17三层。后两层为薄煤层,煤层稳定,煤厚为0.87～1.35m,倾角2°～18°(仅鲍店矿为18°)。薄煤层在兖州煤田占总储量的23.8％,在济宁东区煤田占总储量的35.8％。兖州局7对生产矿井中有3对是薄煤层矿井,另外4对综采大型矿井后期要维持能力,也都存在厚薄配采的问题,有的还有以薄为主的趋势。如果薄煤层回采工艺没有重大突破,矿井
Yanzhou Mining Bureau main mining coal seam with 3,16,17 three. The latter two layers are thin coal seams with stable coal seam with coal thicknesses of 0.87-1.35m and dip angles of 2-18 ° (only Baodian mine is 18 °). Thin coal seams account for 23.8% of the total reserves in Yanzhou Coalfield and 35.8% of the total coal reserves in the Jining East District. Three of Yanzhou’s 7 pairs of production mines have thin coal seam mines and the remaining 4 pairs of large-scale fully mechanized coal mines have to maintain their capacity at the later stage. All of them also have the problem of thick coal mining and some thin-dominated ones. If there is no major breakthrough in the mining process of thin coal seams, mines
