为了改善沿倾斜向下开采工作面的装煤性能和提高工作面产量,曾经在施泰因部长煤矿艾克霍夫EDW—170L采煤机上,用各种不同的滚筒基体作试验比较。滚筒基体分圆柱形和指数曲线形两种,但在其他结构和截齿排列方面,则完全相同。这种试验比较系在奥斯特弗尔德煤矿沿水平回采工作面的基础上进行 In order to improve the performance of coal charging along the sloped mining face and to increase the working face productivity, a variety of drum substrates were used for comparison on the Eckhoff EDW-170L shearer at Stein’s Minmetals Coal Mine. Roller base points cylindrical and exponential curve two, but in other structures and pick arrangement, it is exactly the same. This test was done on the basis of the horizontal mining face of the Austell Coal Mine
