榆神矿区小保当二号井田内赋存有可采煤层9层,分别为1-1、1-2、2-2、2-2下、3-1、4-2、4-3、5-2、5-2下。其中全区可采煤层3层,分别为2-2、4-2、5-2煤层;大部可采煤4层,分别为1-1、2-2下、3-1、5-2下;局部可采煤层2层,分别为1-2、4-3煤层;4-2上、4-4煤层为零星可采煤层。本文主要论述了浅部的1-1、1-2、2-2、2-2下、3-1煤层的厚度、分布范围、变化特征,为煤矿设计和开采提供了基础资料。
There is 9 layers of recoverable coal seam in Yuxian mine area Xiaobo Dangang No.2 Minefield, which are 1-1,1-2,2-2,2-2, 3-1,4-2,4-3 respectively , 5-2, 5-2 under. Among them, three layers of coal seam can be taken in the whole area, which are 2-2, 4-2 and 5-2 coal seam, most of which can be 4 layers of coal, which are 1-1, 2-2, 3-1, 2; local recoverable coal seam 2, respectively, 1-2,4-3 seam; 4-2 on the 4-4 coal seam is sporadic coal seam. This paper mainly discusses the thickness, distribution range and variation characteristics of 1-1, 1-2, 2-2, 2-2 and 3-1 coal seam in the shallow part, and provides the basic data for coal mine design and mining.
