摘要
马脊梁矿现主要开采14-3~#层,但14-3~#层煤层厚度在1.10~5.40m范围内变化较大,煤层形态、厚度、变化规律难已掌握,因此,地质资料的详实与否,是指导生产和科学决策的重要依据。
Majiliang mine mainly mine 14-3 layer, the 14-3 layer coal seam thickness is in 1.10M -5.40m, the thickness change range is great, it is difficult to grasp the seam form, thickness and variation rule, therefore, the detailed geological data is an important basis for guiding the production and scientific decision-making.
