APPLICATION OF PLOW MINING IN THIN-SOFT SEAM WITH HARD ROOF
Plow is one kind of coal winning machinery that has been widely used in mining thin seams in many countries. Based on the application of plow mining in China, the calculating method on aggregative indicator of seam plowability is probided. Herein, plowability of thin seams is divided into five categories, i.e., most easy to plow, easy to plow, normal to plow, difficult to plow and extremely difficult to plow. Using this method, the plowability for thin seams in Caoyao Coal Mine of Yima Coal Group, China is calculated. The calculated result indicates that the plowability of thin seam belongs to the category of normal to plow. This method provides the theoretical basis for the optimization of the schemes of coordination equipments of plow mining for thin seam.
