Research on Intrinsic Safety Method for Open-pit Mining

Open-pit mining is a complicated system engineering which has many unsafe factors like large amount of workers, dispersive workplaces, bad natural conditions and involute working environments. It is necessary to seek an effective way to realize intrinsic safety for open-pit mining. In order to promote intrinsic safety of open-pit mining system, intrinsic safety method out of safety theory and practical mining production are combined to form a full implementation system of intrinsic safety method for open-pit mining. Then the main implementation contents are systematically analyzed. It is thought that intrinsic safety method can help system designers and administrators to take appropriate treatments against accidents. The danger of open-pit mining system can be reduced to a set target or an acceptable level by means of reducing probability and severity of accidents. Its application in open-pit mine will help to manage unsafe factors, reduce danger, establish long-term safety mechanism and eventually improve the level of intrinsic safety of open-pit mining system.
