关于综采工作面二切眼充填材料的选择方案探讨

Discussion on the Selection of Filling Materials for the Secondary Cut in the Fully Mechanized Face

为了保证回采工作的顺利进行,减少矿压带来的影响,通常会采用合适的工程技术措施进行处理,针对我矿8201工作面的实际情况,决定采用二切眼煤体再造技术进行填充,而填充材料的配比的抗压强度则成为技术可行性的关键因素。

In order to ensure the smooth progress of mining work and reduce the impact of mine pressure,appropriate engineering and technical measures are usually adopted to deal with it.According to the actual situation of 8201 working face in our mine,it is decided to adopt the secondary cut coal body reconstruction technology for filling,and the compressive strength of the ratio of filling materials becomes the key factor of technical feasibility.
