以巨野煤田重力资料为主，结合钻井、地质、地震测量和前人研究成果，对研究区的重力场进行了研究，推断了研究区的断裂构造，拟合求解了以石炭-二叠系为沉积中心，奥陶系为基底、石炭-二叠系为中间层、中-新生界为盖层等3个密度层。研究区的主要断裂方向为近SN向断裂，它们为区域性大断裂，不仅控制了研究区煤层的分布特征，也控制了岩浆带的展布。研究区发育有巨野和汶上-宁阳两个潜凹，属于中生代断陷沉积盆地。潜凹内从东往西，沉降幅度逐渐增大，沉积物厚度由薄变厚。并形成了以奥陶系马家沟组为基底，以石炭-二叠系太原组和山西组为主要含煤系岩层，以中-新生界为盖层的沉积构造特征。

Based on gravity data of Juye coal field, combined with drilling, geology, seismic surveying and predecessors' studying results, the gravity field of the research region was studied;the fracture structure of the research area was concluded. Three density layers were fitted to solve by using Permian-Carboniferous as sedimentary center, Ordovician as basement, Permian-Carboniferous as interlayer, Mesozoic-Cenozoic as cap rock. The results show that the main fracture direction in the study area is nearly NS-trending fault;they are the regional great faults, which not only control the distribution characteristics of the coal seams in the study area, but also control the distribution of magmatic belt. Development in the study area has Juye and Wenshang-Ningyang two latent concaves, belonging to Mesozoic fault depression basin. Sedimention range gradually increases from east to west in hidden inside concave, sediment thickness is from thin to thick.And sedimentary structure characteristics with Majiagou group of Ordovician as the basement, Taiyuan and Shanxi group of Permian-Carboniferous as the main containing coal measures strata, Mesozoic-Cenozoic as the cover have been formed.
