70～80年代自行研制开发的ZB2-100型单滚筒采煤机，BMD-10

The ZB2-100 single-drum shearer, the BMD-100 single-drum shearer, and the BM-100 double-drum shearer developed independently in the 70s and 80s. The installed power of ZB2-100 type shearer is 100kW, chain traction, hydraulic speed adjustment plus gear deceleration, traction force 90kN, traction speed 0 ～ 2.4m / min. It can be applied to the gently inclined thin coal seam with medium mining height below 0.75 ～ 1.3m. This coal mining machine is only used in Zibo Mining Bureau and has not been promoted.

70-80 son self-developed ZB2-100 single roller shearer, BMD-100 single roller shearer, BM-100 double roller shearer. ZB2-100 type shearer installed power 100kW, chain traction, for hydraulic speed control plus gear reduction, traction 90kN, traction speed 0 to 2.4m/min. Can be applied to the mining height of 0.75 to 1.3m of the medium-hard sub-slow tilt thin seam, the shearer is only used in Zibo Mining Bureau, has not been promoted.

Zb2-100 type single drum shearer, bmd-100 type single drum shearer and BM-100 type double drum shearer developed by ourselves in 1970s-1980s. The installed power of zb2-100 shearer is 100kW, chain traction, hydraulic speed regulation plus gear deceleration, traction force is 90kN, traction speed is 0-2.4m/min. It can be applied to the mining of gently inclined thin coal seam with the height of 0.75-1.3m, which is below medium hard. The shearer is only used in Zibo Mining Bureau and has not been popularized.<br>
