Caterpillar recently signed another contract to deliver an automated longwall plow system to a Chinese company, Gasification Co of Lvliang Dongyi Group. The system marks the eleventh plow system from DBT/Bucyrus/Caterpillar destined for Chinese mines. The system will be delivered in the March quarter of 2013 and will go to work in the Xinyan mine in Shanxi province, China.
The system will mine a metallurgical coal seam with height of 1.0-1.2 m, and the face length will be 240m. The Cat GH800 plow will be paired with a Cat armoured face conveyor using PF3 line pans, and the Cat PMC-R roof support control system will manage roof support advance.
Tiefa Coal Mining Group, with a 50% share in the joint venture project with Dongyi, owns four such systems already and has publicly indicated that the plow systems enable them to profitably mine thin seam reserves that otherwise would be uneconomic.
