摘　　要：煤炭是新疆的主要能源,在自治区一次能源消费结构中所占的比重在60%以上。煤炭工业作为能源基础产业,对自治区国民经济和社会发展起着重要的支撑和保障作用。目前,新疆区内煤炭资源预测储量2.19万亿t,占全国煤炭资源预测储量40%以上,位居全国首位。为合理利用新疆沙湾市沙湾煤矿区煤炭资源,促进区域经济和社会发展,通过地质调研和资料整合,从煤炭资源评估、地质评估以及其他资源3个方面展开对研究区的煤炭资源开发可行性分析,研究结果表明:(1)研究区各煤层显微组分主要以镜质组分、惰质组分为主,整体属于低水分、低灰煤、中高—高挥发分煤;(2)研究区井田内累计查明资源量15485.3万t,其中:探明资源量9174.7万t(控制资源量1211.0万t;推断资源量5099.5万t);(3)研究区水文地质类型以裂隙含水层充水为主,水文地质条件中等的矿床,总体上全区属泄水地貌,各煤层顶底板多数岩石具有中等的抗压强度;(4)新疆沙湾煤矿区东区榆树沟整合井田煤炭资源开发在资源储量和煤质特征方面具有可行性,但在实际开发过程中充分考虑并妥善处理该区域复杂的地质构造问题,以及由此衍生的环境影响挑战,确保开采活动的可持续性和安全性。Coal is the main energy in Xinjiang,which accounts for more than 60%of the primary energy consumption structure in the autonomous region.As a basic energy industry,the coal industry plays an important role in supporting and guaranteeing the national economic and social development of the autonomous region.At present,the predicted reserves of coal resources in Xinjiang are 219 trillion tons,accounting for more than 40%of the predicted reserves of coal resources in the country,ranking first in the country.In order to rationally utilize coal resources in Shawan coal mine area,Shawan City,Xinjiang,and promote regional economic and social development,the feasibility analysis of coal resources development in the study area is carried out from three aspects of coal resource assessment,geological assessment and other resources through geological investigation and data integration.The research results show that:(1)The maceral components of each coal seam in the study area are mainly vitrinite and inertinite,which belong to low moisture,low ash coal and middle to high volatile coal as a whole;(2)The total identified resources in the well field of the study area are 154.853 million tons,of which:91.747 million tons Controlled resources of 12.110 million tons;Estimated resources of 50.995 million tons;(3)The hydrogeological type of the study area is mainly fractured aquifer filled with water,and the hydrogeological conditions are moderate.On the whole,the whole area belongs to drainage landform,and most of the rocks on the top and bottom of each coal seam have moderate compressive strength.
