我矿地处一老年期的丘陵地形,矿区总面积为东西12公里,南北7公里,总计84平方公里。矿区煤田属于上侏罗纪相沉积,煤田构造呈近于东西的向背斜构造,分为南、北两含煤条带。因受火山喷出与造山运动的影响,所以该区中小型的褶曲与断层构造较为复杂。含煤层可分为三组:即上部穆棱含煤组,厚500～600米;中部鸡西含煤组厚500至600米;下部滴道含煤组厚200～300米。各
My mine is located in a hilly terrain of old age, the total area of mining area is 12 km from east to west, 7 km from north to south, a total of 84 square kilometers. The coalfield belongs to the Upper Jurassic facies sedimentary. The structure of the coalfield is nearly anticline to east-west structure and is divided into south and north coal-bearing strata. Because of volcanic eruption and orogeny, so small and medium-sized folds and fault structure is more complex. The coal seams can be divided into three groups: the upper Muleng coal-bearing group with a thickness of 500-600 meters; the middle Jixi coal-bearing group with a thickness of 500-600 meters; and the lower drip coal-bearing group with a thickness of 200-300 meters. each
