On the base of extensive field investigation of man-made debris flow in Shenfu-Dongsheng minesite, and according to its characteristics and processes, the system controlling model were respectively summarized up with theory of many levels controlling system, and the peculiarities of system controlling of man-made debris flow in Shenfu-Dongsheng minesite were generalized. The main aim of system harness of man-made debris flow is to make potential debris flow not broken out and present debris flow decreased.
