Embodiment Construction

[0041] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0042] The invention provides a mechanized non-waste mining method for deep metal deposits.

[0043] Such asfigure 1 As shown, the method includes the following steps:

[0044] S1: Stope design and mining construction:

[0045] Mining is carried out along the direction of the ore body, and the stopes are arranged according to the thickness of the ore body. The number of stopes is an even number, and mining is carried out in a downward horizontal layering manner. Each section and middle section are constructed with a stope connection along both sides of each stope. There is no connecting road in the middle; ventilation shafts run through each middle section, and ventilation shafts are arranged at the footwall of each section, and air ducts are used for l...

Abstract

The invention provides a mechanized waste-free mining method for deep metal deposits, which belongs to the technical field of mining. In this method, the stope design and mining engineering construction are carried out first, and then mechanized mining is carried out. The full-face hard rock roadheader and the tunneling trolley are used to jointly mine the ore, and then the ore and waste rock are transported. After the recovery level, the belt conveyor is used to continue to transport the ore to the heap leaching chamber. During the transportation process, intelligent sorting is carried out to separate the ore waste. Further, the location with stable surrounding rocks is selected to arrange the leaching recycling chamber and the ore storage chamber. Carry out leaching cycle recovery, and finally mix the waste rock generated in the production process and the ore after mineral extraction, and then carry out waste rock filling. The method can realize safe and efficient continuous mining of deep ore bodies, achieve the purpose of waste-free mining, reduce production costs, and eliminate surface pollution and safety threats.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a mechanized waste-free mining method for deep metal deposits. Background technique [0002] Metal mineral resources are an important foundation for the economic development of a modern country. As the shallow deposits are gradually exhausted, most metal mines gradually develop into underground mining and deep mining. For a long time, environmental pollution and ecological damage are unavoidable accompanying problems of mining activities. Traditional mining activities destroy surface vegetation, produce dust, solid waste, wastewater, waste gas and other pollutants, cause ground subsidence, slope instability, debris flow and other engineering disasters, and seriously pollute the environment. Therefore, in order to realize the sustainable development of the metal mining industry, the green and waste-free mining mode has become an inevitable mode in the future. [0003] Traditiona...
