从马儿庄勘查区的区域地质背景入手,对勘查区含煤地层、构造、岩浆岩和含煤性等特征进行了系统的研究,并借助于该区开展的钻探、地震等工作,对勘查区煤炭环境地质问题进行了分析。研究表明:马儿庄勘查区主要含煤地层为延安组,该组地层共含煤37余层,可采10层,可采煤层平均总厚度17.34 m,可采含煤系数4.02%。勘查区煤层开采常会引起地面塌陷等地质灾害,但对生态环境、地表水及潜水的水质的影响较小。煤及煤矸石中含有一定量的硫、磷、氯、砷等金属或硫化物以及一定量的放射性元素,在煤炭开采过程中,应做好相关防范,确保施工人员的安全和对环境的影响。
Starting from the regional geological background of the Mazhuang prospecting area, the characteristics of the coal-bearing strata, structure, magmatic rocks and coal-bearing properties in the exploration area are systematically studied. Based on the drilling and earthquakes carried out in this area, District environmental geological problems of coal were analyzed. The study shows that the main coal-bearing formation in Mazhuang exploration area is Yan’an Formation, which contains 37 layers of coal and 10 layers of recoverable coal. The average thickness of recoverable coal layers is 17.34 m and the recoverable coal coefficient is 4.02%. Coal mining in the exploration area often causes geological disasters such as ground subsidence, but it has less impact on the ecological environment, surface water and the quality of submersible water. Coal and gangue contain a certain amount of sulfur, phosphorus, chlorine, arsenic and other metals or sulfides and a certain amount of radioactive elements in the coal mining process, should be well-prepared to ensure the safety of construction workers and the impact on the environment .
