一、回采工作面技术滚筒采煤机发展情况:1976年起,德国发展电牵引滚筒采煤机。目前,美国和澳大利亚也使用电牵引滚筒采煤机。将来,电牵引滚筒采煤机肯定会在世界上得到普遍使用。艾柯霍夫公司EDW300—LN型薄煤层电牵引双滚筒采煤机已得到普遍使用,两个截割滚筒电机采用中央布置方式。EDW150—2L—2W型双滚筒釆煤机电机采用横向布置,有两个分开的截割电机,这种电牵引采煤机使用得很好,但在极限负载,如在过岩石断层和随巷道一起截割时直流牵引电机寿命不够理想。
First, mining face technology drum shearer development: Since 1976, the development of Germany’s electric traction drum shearer. Currently, the United States and Australia also use electric traction drum shearer. In the future, electric traction drum shearers are sure to gain widespread use in the world. Ekerhof EDW300-LN thin coal seam electric double drum shearer has been widely used, the two cutting drum motor adopts the central arrangement. EDW150-2L-2W dual-drum preclude the use of horizontal motor drum motor, with two separate cutting motor, the electric traction shearer well, but at the limit load, as in the rock fault and with roadway When cutting together, the DC traction motor life is not ideal.
