摘要
薄煤层开采中的装煤性能是影响采煤效率的主要因素,针对工作面倾角对装煤量的影响进行仿真模拟。结果表明,在推挤装煤中,随着工作面倾角的增加,装煤量呈逐渐减小的趋势,工作面倾角为-20°时的装煤量是20°时的1.74倍;在抛射装煤中,随着工作面倾角的增加,装煤量的整体差值不大,仅在-20°倾角时的装煤量较大。
The coal loading performance in thin coal seam mining is the main factor affecting the coal mining efficiency. The influence of face inclination on coal loading is simulated. The results show that in the push coal loading, the coal loading amount decreases gradually with the increase of the working face inclination angle. When the dip angle of the working face is -20 °, the coal loading is 1.74 times that of 20 °. In the ejection coal loading, with the increase of the working face inclination, the overall difference of coal loading is small,and the coal loading is large only at the inclination of -20 °.
