Shijiazhuang Coal Mine Machinery Replacement Roadheader "Change Face"

Experts from the National Mine Product Safety Marking Center performed performance testing on the roadheader after “face change”

Shijiazhuang Coal Mining Machinery Co., Ltd. further accelerated the pace of upgrading products in the pioneering activities. Recently, it changed the vertical axis type 260 rock tunneling machine that was just introduced last year to “face change” to a horizontal axis type so that the machine could effectively cut rock. Cut hardness increased from the original f10 to f13.
