EBJ—160型半煤岩掘进机在大同矿务局永定庄矿的试验,在以切割抗压强度为100MPa左右的粉砂岩为主的半煤岩巷道中掘进,取得了月进400m以上的好成绩,说明该机基本能适应大同煤层与围岩的半煤岩巷道掘进。
The trial of the EBJ-160 semi-coal tunnel boring machine at the Yongdingzhuang mine in Datong Mining Bureau was carried out in a semi-coal rock roadway dominated by siltstone with a compressive strength of about 100 MPa and a monthly advance of more than 400 m was achieved Results, indicating that the machine can basically adapt to Datong coal and rock semi-coal roadway heading.
