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.

然而，全球一体化对我国矿业带来的挑战，以及我国矿山片面追求经济效益、安全管理和环境保护意识的淡化、开采技术和设备的相对落后以及承包、转包、租赁等经营管理形式的多样化，安全监管手段滞后，造成矿难事故频频发生，给国家、矿山企业以及附近的广大人民群众造成了巨大的生命财产和经济损失，产生了不良的社会影响，严重制约了国民经济和矿山企业的可持续发展。

In order to solving the problem on scarcity of backup resources of the depleted mines in Lujing uranium ore-field and using the existing sub-profitable type of geological reserves, it is suggested that the high grade of profitable type of deposits should be explored around the exhausting mines so that the production of the mines could be profitable by the pithead heap leaching mining method with arrangement groups of both sub-profitable and profitable type of ores.
