炮采工作面攉煤机主参数的理论计算

Theoretic calculation of main parameter of the coal shovel for blasting mining face

针对我国目前炮采工作面装煤的现状，设计出了一种新型便携式炮采工作面攉煤机，对实现炮采工作面装煤机械化有促进作用。并论述了该机的工作原理，推导了装煤能力和装煤率以及刮板的运行阻力的理论计算公式。

A new-type portable coal shovel for blasting mining face is worked out in order to improve working surroundigns, which will play a determinately stimulative effect on loading coal mechazation for blasting mining face. In this paper, the Operating principle of the new type of coal shovel is discussed. And then, the theoretic estimating formulas for loading ability, loading ratio and working resistance of drawing plank are deduced.
