According to the analyses on the geochemical distinction of the minerogentic grological background of HeTai goldmine deposit and to the studies on the minerogentic hydrothermal source,physicochemical condition,mineral istope,and so on,it point out the researching manner and technique route of ore-searching in the deep part by utilizing the geochemical method.
The column introducing devolopable procedure and successful representive in production of Technique extracting gold from gold ore with cyanide was made.Each technique of cyanide were compared.I laid special stress on character of each technique of cyanide and each key factor which we should pay attention to.I bring forward devolopable direction of technique extracting gold from now.
The support techniques such as belting,wire-rope bolting and guniting ore commonly used under the conditions of bad stability of stope orebody rocks in gold mine for reinforing rocks stability,quarranting working safety,mining depletion and dilution to raise economic effect.In this paper,they are summarily introduced and assessed.
This paper used the concrete data of south-Africa gold mine on deep mining,enpounded the speciality about the technique of ventilation on deep mining,summarily introduced the ventilation method and ventilation planning on deep mining.Combining the practical case of meteline mine in China,pointed out the research derection at ventilation technique in deep mining at meteline mine in China.
The paper deals with the way to establish the analog dynamic economic model of gold mine with Excel software,which has two outputs of form and diagram,and state practical meaning.
