GIANT MINER

picture @Edo LGA in a Dolomite Quarry Dewatering operation is one of the most sensitive and continuous operation during raining season. The approach to this operation depends on the mine design, mining method and other factors including the mine terrain. Most surface mine can not escape the challenge of surface water inflow but can be overcome through proper dewatering plan. Dewatering is define as the process of removing unwanted collection of water in the mine. It describe as the approach use in remove water from mine pit so as to gain access to the ore deposit. In view of surface Mining methods, which involves the extraction of deposit with less overburden thickness. The mining approach adopt in surface Mining methods are such that a cavity is advance into the Earth crust. Such cavity has lower attitude compare to the nearby environment which prompt the collection of water into it. Mine out area (stope, pit) recieve water from: 1. Surface run-off water 2. Direct precipit...

Stemming in blasting is very important and affect not only the efficiency of the blasting but also the impact of the blasting on the environment. By simple definition, stemming is a confinement process done by the use of innert materials to confine explosive charge within the drill hole during charging. The define function of stemming is to: 1. Ensure the explosive charge is confine within the hole socket so as to avoid poor distribution of explosive release shock energy. 2. Prevent the escape of shock wave into the environment and causing airblast and other environmental impact. Stemming can be top confine or inter-column charge confined. In case of decking charge pattern, each explosive charge column is separated by innert material to reduce the charge weight and also to ensure effective distribution of shock energy along the hole column. In the case of decking, stemming is use to confine and to separate upper charge column from the lower charge column. Stemming materials...
