Non-explosive mechanical rock breaking circulating drift filling mining method

Abstract

The invention discloses a non-explosive mechanical rock breaking circulation drift filling mining method which comprises the steps that stopes are arranged along the trend of an ore body, no stud is reserved between the stopes, the stopes are stoped and filled in a layered mode from bottom to top, a cantilever type heading machine is adopted in the layers for drift type cutting ore breaking stoping, and the drift is circularly stoped layer by layer on the stope layering plane from outside to inside. And in the recovery process, trackless mining transportation equipment follows ore removal, and access road partition filling is carried out. The non-explosive mechanical cutting ore breaking mode is adopted for stoping, and the method has the advantages of being safe in stoping operation, high in efficiency, low in cost and the like.

Description

technical field [0001] The invention belongs to the field of underground mining, and relates to a non-explosive mechanical rock-breaking circulation approach filling mining method, which is particularly suitable for the mining of ore bodies with low rock hardness. Background technique [0002] At present, the metal and non-metallic hard rock mines still mainly use the drilling and blasting method. Rock drilling equipment is used to construct various types of blastholes. The blastholes are filled with detonators and explosives to blast the ore. Mining is carried out. Practice has shown that the traditional drilling and blasting method mainly has the following shortcomings: (1) The drilling and blasting method uses explosives and detonators to blast the ore, and the safety is poor. On the one hand, the pyrotechnic product itself has potential safety hazards, on the other hand, a large amount of toxic and harmful gases will be generated after the explosive blasting, and at the...

Problems solved by technology

Practice has shown that the traditional drill and blast method mainly has the following disadvantages: (1) The drill and blast method uses explosives and detonators to blast the ore, and the safety is poor

On the one hand, there are potential safety hazards in pyrotechnics, on the other hand, explosives will produce a large amount of toxic and harmful gases after blasting, and at the same time cause irreversible damage to the surrounding rock mass, affecting the stability of the stope or roadway

(2) Drilling and blasting mining, such as rock drilling, blasting, and ore extraction, are scattered and discontinuous, and the production management is complicated and inefficient, which is not conducive to the realization of automation and intelligence

(3) Drill and blast mining workers have high labor intensity and poor working environment

[0006] For this reason, the present invention provides a non-explosive mechanical rock-breaking circular approach filling mining method, which aims to solve the problems of poor safety, poor operation continuity, high labor intensity and poor working environment in the traditional drilling and blasting mining of hard rock metal mines. and other issues, and at the same time through the innovation of engineering layout, give full play to the efficiency of the cantilever roadheader
