大采高综采面推进速度与周期来压步距关系分析

Analysis of Relationships between Propulsion Velocity and Periodic Weighting Length at Fully-mechanized Mining Face with Large Mining Height

以察哈素煤矿首采工作面为工程背景,通过对工作面支架工作阻力监测以及推进数据的收集、整理和分析,对大采高综采超长工作面推进速度与周期来压步距间的关系进行了深入细致的研究,得到了周期来压步距与推进速度的函数关系式。

The initial mining face of Chahashu mine is taken as an engineering background, the working resistance of support at working face is monitored, and propulsion data is collected,reorganized and analyzed. Then meticulously studies the relationships between propulsion velocity and periodic weighting length at ultra-long fully-mechanized mining face with large mining height, and finally gets the functional relation formula between periodic weighting length and propulsion velocity.
