In order to realize coal mining in safety without moving villages, increase coal recovery ratio, solve the conflict of mining and panel relays, the scheme of paste backfill mining under villages in Xiaotun coal mine is executed, and the surface subsidence observation lines on the surface of the mine are established and timely monitored. Based on the results of the surface movement observation, the...
Based on the theoretical analysis of the feasibility to use the Vanadium sludge of converter to make vanadium-recovery coolant, ingredient of a cold-pellet suitable for vanadium recovery process has been developed. Industrial production and practice indicates that the cold-pellet for vanadium recovery could replace pig iron partly, the consumption for pig iron reduces from 14.7 kg/ton to 5.1 kg/ton...
This paper described an agricultural mobile robot which was refitted by FT4040 tractor. A position calculation method using inner information was proposed, and the tractor straight-line tracking control was researched by fuzzy control theory. The position and posture of the tractor were calculated using the information which detected by the inner sensors, a fuzzy controller was designed for straight-line...
