一、概况平庄煤田位于内蒙古自治区赤峰市南东,约55km,属赤峰市所辖。按地质力学观点,则位于天山———阴山纬向构造带,与新华夏系第二沉降带的复合部位。平庄煤田大致呈北东———南西向展布,为一倾向Nw的单斜构造。五家矿区位于平庄煤田的西南端,一井则位于五家矿的东北部。煤层走向大致为NE,局部受断层影响变为西,呈缓慢的“s”型。倾向西,倾角一般8～10度。断层以倾向和斜交断层较为多见。煤系地层属上侏罗系
I. Overview Pingzhuang Coalfield is located in the south east of Chifeng City, Inner Mongolia Autonomous Region, about 55km, belongs to Chifeng City. According to the geomechanical point of view, it is located in the Tianshan --- Yinshan weft tectonic belt, and the second part of the Xinhuaxia subsidence zone complex. The Pingzhuang coalfield is broadly northeast to southwest and is a monoclinic structure with a tendency of Nw. The five mines are located on the southwestern tip of Pingzhuang Coalfield while the first well is located in the northeast of Wujia Mine. The coal seam is roughly NE-trending and locally affected by the fault becomes westward, showing a slow “s” shape. Tendency west, dip generally 8 to 10 degrees. Faults tend to dip and cross faults are more common. Coal strata belong to the Upper Jurassic
