肥城煤田下组煤底板隔水能力影响因素分析

THE FACTORS INFLUENCING THE FLOOR WATERRESISTING PROPERTY IN FEICHENG COAL FIELD

分析了肥城煤田下组煤开采时隔水底板岩层阻水能力的影响因素，认为底板隔水层岩性的不均匀性、煤田内的重力滑动构造、矿压作用及承压水的作用是削弱该煤田隔水底板阻水能力的主要影响因素。

The article analysis the factors which influence the floor waterresisting property in Feicheng Coal Field during mining the coal layer in Taiyuan formation,and thinks that the unhomogeneity of floor rock,the gravitygliding structure in the coal field,the underground pressure and the confined water are the main influencing factors which weaken the floor waterresisting ability.
