Abstract

The invention provides a small corner ore medium-length hole mining method, and relates to the technical field of mining methods. By adopting three layers of medium sections, a main ore body is linkedto a development roadway, the mining and developing work amount is lowered, the mining cost is reduced, and a ventilation system is easily formed; VCR pull trough explosion is adopted for creating the compensation space, side collapse adopts scallop hole ore breaking, hole arrangement is more flexible, adaptability is high, the resource recycling rate is increased, and the ore grade is improved;due to the unilateral access, trackless equipment ore removal is achieved, and the mechanical level is greatly increased.

Description

technical field [0001] The invention relates to the technical field of mining methods, in particular to a medium-long hole mining method for small corner ore. Background technique [0002] With the continuous expansion of resource demand and the deepening of resource development, the reserves of thick and easy-to-mining ore bodies are becoming less and less. The main ore body resources of many old mines have been fully developed, and the production area has shifted to the surrounding corners and sporadic ore bodies. , and there are a large number of corner ore bodies around the main ore body of some new mines, how to effectively develop this part of the resources is crucial to the overall mining of the mine. Reasonable mining of corner ore has the advantages of supplementing the production capacity of the main ore body, prolonging the service life of the mine, and improving the recovery rate of mineral resources. However, the corner ore has mining difficulties such as small ...
