摘　　要：北塔山煤矿区位于北塔山褶皱系西部的凹陷内,煤炭资源丰富,煤质特征好,通过对该区构造特征和可采煤层煤质资料分析研究,从煤岩学和煤化学方面总结煤矿区的煤质特征及变化规律。分析高惰质组和低灰分含量成因,泥炭沼泽形成时期盆地基底沉降速率较慢,泥炭沼泽表面长期处于沼泽的潜水面之上,具相对氧化的高位沼泽泥炭环境。由于受阚尔甫托浪格簸箕状向斜和东部F1断层控制,煤质分布具有西南边缘和东部断层一带灰分高、发热量低,硫分中间低、四周高的特征。Beitashan coal mine area is located in the depression in the west of the Beitashan fold system.It is rich in coal resources and has better coal quality characteristics.Through the analysis of the structural characteristics and coal quality datas of the mining seam in this area,the coal petrography and coal chemistry are studied to summarize the coal quality characteristics and change rules in the coal mine area.Based on the analysis of the origin of high inertinite and low ash content,the subsidence rate of basin basement was slow during the formation of peat bogs,the surface of peat bogs was on the water surface of the swamp for a long time,and there was a relatively oxidized high bog peat environment.Due to the control of Kanerputuolangge dustpan syncline and eastern F1fault,the coal distribution is characterized by high ash content,low calorific value in the round the southwest margin and the eastern fault area,with the characteristics of the sulfur content is low in the middle and high around.
