菏泽地区张湾煤田主要可采煤层是山西组的3煤（包括3上和3下煤层），煤层特点是赋存面积大、埋藏深、煤层厚度大、结构简单，研究3煤层在井田内构造、深度、厚度、结构、煤质、物性、开采技术特征以及成煤环境分析，对今后煤层开发有着重要的指导意义。%Chang Wan coalfields Heze area is looking for coal Juye periphery of the most successful examples, the main coal seam of coal in Shanxi Group 3 （including the three under and in three coal）, coal occurrence is characterized by large area, buried deep, coal seam thickness is large , simple structure, mainly coking coal grades and 1 / 3 coking coal, and therefore the study within 3 coal seam in the Coal Mine structure, depth, thickness, structure, coal quality, physical properties, technical features, as well as into the coalmining environmental analysis on the future development of coal seam has an important guiding significance.
