Problems solved by technology

At present, the mining industry is facing many problems on the road of sustainable development. First, the reserve reserves of mineral resources are insufficient.
Second, the existing mineral resources are not effectively utilized and are seriously wasted
Under the condition that the current gold price continues to rise, the maximum economic benefits can only be obtained by increasing the production capacity. However, the tailings layered filling mining method that many mines in China have been adopting has low efficiency, high cost and poor safety.

Embodiment Construction

[0017] 1. Mining and cutting project layout:

[0018] Five-section hanging wall stope: Excavation roadway along the vein is excavated between the upper and lower walls, and two access roads through the veins are excavated in this exit roadway and the connecting road between the original upper and lower walls to form three access roads. An artificial point column is arranged near the connecting road between the upper and lower walls, and the excavation slope is 90 degrees to cut the patio to the six-section hanging wall stope to form the initial free surface.

[0019] Five-section footwall stope: the original stope connecting road is excavated with an ore exit route to the stope, and three artificial point columns are arranged in the stope to form three access routes and six cutting trenches with the original point columns, and the excavation slope is The 90-degree cut from the patio to the footwall stope of six sections forms the initial free surface.

[0020] Six-section sto...

Abstract

'pre-control roof open stoping spallation subsequent filling mining method' is characterized in that advantages of backfill mining method and spallation mining method are adopted, respective disadvantages are made up, a bran new mining technology is formed, and the method has the advantages of low ratio of mined tonnage to development, high efficiency, good safety and strong practicability and is especially applicable to the mine industry.

Description

Technical field: [0001] The invention relates to a mining method, in particular to a pre-controlled headspace caving followed by filling mining method. Background technique: [0002] With the disappearance and non-renewability of mineral resources, there are fewer and fewer available mineral resources, and mining is becoming more and more difficult. At present, the mining industry faces many problems on the road of sustainable development. First, the reserves of mineral resources are insufficient. Second, the existing mineral resources are not effectively utilized and are seriously wasted. According to statistics, the utilization rate of mineral resources in my country is only about 50%, and some mines are only 40%. Under the condition that the current gold price continues to rise, the maximum economic benefits can only be obtained by increasing the production capacity. However, the tailings layered filling mining method that many mines in China have been using has low eff...
