巩义鑫 China Machinery Mining Knowledge Forum: Principles select mining methods followed. According to the characteristics of deposits in ore grade level of 80 Cinder machine manufacturers, distribution uniformity and optional features, according to the known deposits in the exploitation of similar quality indicators mine, with several groups of the lowest grade and industrial grade boundaries, choose a representative area deposits Savings were calculated and average grade, and according to national needs, the degree of resource utilization 80 Cinder machine parameters, the scale of production, mining, ore processing technology conditions, the cost of production shafts 80 Cinder machine, investment results and other factors, for each group Indicators Programme comprehensive comparison and choose the most reasonable option. Gongyi City Xinhua Machinery Factory is a leading manufacturer of slag machine, the production of slag machine, picking mining machine products sold abroad, small water conservancy project construction can be used to control the diesel-powered tire Pa mining machine, which has Hydraulic walking, digging acquisition, belt conveyors, clear bottom, and other functions. Gongyi Xin Hua Machinery Mining Knowledge Forum, mine exploration program approval. Determine the ore body (outcrop) coordinates → with coordinates to County Land Resources Bureau check whether there is overlap → tenements blank area in the case of applications for prospecting and selling ready to start selling range → OK → Gravitropism inflection point coordinates belongs County towns made the transfer request and obtain Reply → appropriate county bureau reported in document form State Land Office → State Land Bureau reported Provincial Department to file the form by auction record → → complete prospecting made (pre-investigation, survey, detailed investigation, exploration) after work → mined mineral mining scoping obtain approval → → submit (reserve verification report, the development and utilization plan, mining design, environmental recovery and management, land reclamation program, safety evaluation) and other competent authorities of the relevant reports and information requirements apply for a mining license card.

Mining companies are mining ore or mineral raw materials production units, generally including the management of one or several open pit. Pit mine and production needs and to ensure a variety of auxiliary plant. Mined underground mining can be divided into day and fill mining. Deposits choose a pit (hole) mining or mom mining, mine should be based on the terrain to look, deposit geology and economic conditions exist Bin determined. If the deposits in the fill surface or shallow buried. It is suitable for open-pit mining. If deeply buried deposits in 80 Cinder machine, you can only use pit mining. But some deposits in only to see both front and burying mining, you can pit mining. Generally fill mining pit mining costs are lower than some of the economic Some cost-effective, but not necessarily, if the open-pit mining of the brake from large pots, from mining costs. It is necessary to consider the use of pit mining, and some may be part of the implementation of the female deposits in mining. Another pit mining practice. So for a deposit in the manner in which mining, geological conditions and topography from economic and other aspects were analyzed and compared in order to determine. 80 high-quality machine Cinder Cinder machine _ 80 _ Lincang mining machine installed by Gongyi City Xinhua Machinery Factory. Gongyi City Xinhua Machinery Factory (www.gyxinhua.com) strong, credible, in Zhengzhou, Henan handling equipment industry has accumulated a large number of loyal customers.
