通过对西村详查区内二1煤层的聚煤特征、煤层发育情况以及后期构造变化等因素的研究,分析了二1煤层厚度变化特征和影响二1煤层厚度变化的因素,分析结果表明,二1煤层厚度变化的主要原因是原生沉积因素和后期构造形变的相互作用,该研究对下一步井田的开拓布置、煤炭生产具有较大指导作用。
Based on the study on the characteristics of coal accumulation, the development of coal seams and the later tectonic changes of No.21 coal seam in the detailed investigation area of Nishimura, the variation characteristics of the thickness of No.2 coal seam and the factors affecting the thickness change of No.2 coal seam are analyzed. The results show that, 1 The main reason for the change of coal seam thickness is the interaction between primary sedimentary factors and later tectonic deformation. This research has a great guiding role for the next step of minefield layout and coal production.
