Mining Method Must Meet The Following Requirements

Mining method selected must be able to ensure the safety of workers in the mining production process, with good operating conditions ( such as reliable ventilation dust control measures.proper temperature and humidity.

Security

Mining method selected must be able to ensure the safety of workers in the mining production process, with good operating conditions ( such as reliable ventilation dust control measures.proper temperature and humidity. make heavy mechanized operations.and to ensure that the mine can security continues to produce.such as to avoid massive destruction caused by the pressure of events may prevent landslides and debris flow hazards of surface blasting vibration and may cause postharvest rock movement.to prevent underground floods and fires and other disasters.

ore dilution small

Mining method selection to depleted.high quality ore.ore processing sector to meet the quality requirements . Such as open-hearth rich iron ore mining.waste rock can not make too much powder and mixed with the high rate of ore.the ore in order to have direct access to the open hearth . Depleted ore mine product ( concentrate.number.cost and profitability impact is great . In general, the rate of goods marked ore 15% -20 % or less.

ore mining rate plus

Mineral resources are limited and are not renewable.mining production are of exhaustion.thus requiring higher stoping mining method of choice.in order to make full use of underground resources . In addition to the loss of ore minerals have an impact on costs.should also reduce the total amount of earnings and shorten mine production time. General requirements for ore recovery rate should be above 80 % -85 % of high -grade ore mined value.precious metals and precious metal deposits.they should try to choose a high stoping mining method .

high production efficiency

To select a mining method of production capacity and high labor productivity as possible. Mining methods are different, the same number of stages of the exploitation.production capacity and ore mining blocks blocks can be arranged in a different stage . Generally the number of nuggets in a recovery stage arranged to meet the production capacity of the mine mining method selection criteria to be considered . Back to the mining block length of less than two-thirds share of phase line length is appropriate.

High productivity can reduce the number of simultaneously working nuggets.easy to implement centralized management of mining and mining production in favor of ground pressure management.

high economic efficiency

Economic level mainly refers to the level of mining products into three size and profitability . Profitability indicators of the most comprehensive in nature, such as cost of ore.ore cargo loss and so have an impact on earnings . To select profitable large mining methods.
