摘要
通过对11-2煤层沉积赋存特征、夹矸岩性厚度变化特征、沉积基底及古流水冲蚀破坏作用的研究,讨论了11―2煤层沉积环境及其变化规律,总结了影响采掘的主要地质因素,并据此提出了矿井采掘中相应的管理方法和治理措施,对矿井生产具有一定的指导意义。
Based on the preservative cases of No.11-2coalbed in mine field,the depositional and parting changes of No.11-2coalbed are analysed,and researched depositional environment and change law of the coalbed,and summarized main geological factors to influence loading.Finally the corresponding method of management and measure of harness deal with loading production of mine are submitted.
