And the new transaction ore patterns establish one after another, which causes the mine enterprise to coruscate vital force. However due to mine enterprises one-sided pursue economic efficiency, the safety management and the environmental protection consciousness desalination, the exploitation technology and equipment correspondingly draggle, safety intendance instrument lag as well as the modality of the management and administration diversification such as the contract, the subcontract, the rents and so on, mining accident continually occur. These accidents caused a huge loss of both life and economy to nation, mine enterprises and multitude who live somewhere about mine, brought ill social influence, and badly restricted the continual development of the national economy and mine enterprise.
