According to question existing in China's small and medium-sized coal mine, an intelligent monitoring design based on Single Chip Microcomputer is proposed.

The market demand for coal has increased and coal price was stable. The market share of large and medium-sized coal enterprises was increased while their loss has decreased.

And the Fuzzy-follower is applied in shaft bottom coal conveyor of a medium-sized coal mine and gives good results. Thus, it solves the problem of power balance of double-motor driving system.
