倾斜长壁保护层综采工作面的优化布置

Practice of Removal of a Fully Mechan ized Face under Con-dition of Large Fault

根据打通一矿现有开采技术条件,分析了倾斜长壁保护层综采工作面优化布置,从单面与对拉布置、工作面几何尺寸确定、整段与分段布置、两巷位置的选择四个方面进行了优化研究,满足了弹性生产,提高了经济效益,可供类似条件的工作面参考。

The paper gives a detailed descripti on of the practice how to create condition s for the removal of No.307fully mechanized coal face and how to withdraw powered supports from the face in the event of the existence of fault F4and under the condition of fractured roof.The face removal was smoothly completed by the application of seve ral technological measures and such experience can be used for reference for similar mines.
