Upward horizontal layered filling mining method for non-explosive mechanical rock breaking perpendicular to strike

Abstract

The invention discloses a non-explosive mechanical rock breaking upward horizontal layered filling mining method perpendicular to the trend, which comprises the following steps: arranging stopes perpendicular to the trend of an ore body, arranging a first-step stope and a second-step stope at intervals, firstly mining the first-step stope and filling a goaf, and then stoping the second-step stope and filling the goaf; the stope is stoped from bottom to top in a layered mode, a cantilever type heading machine is adopted for cutting non-blasting ore breaking, trackless mining transportation equipment is adopted for ore drawing, layered cutting ore breaking is conducted, layered filling is conducted after ore drawing is completed, a filling body is maintained to the design strength, then layer transferring is conducted, stoping of the next layer is started, and the steps are repeated till stoping of the whole stope is completed. 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 mining method for vertical horizontal layered filling of non-explosive mechanical rock breaking arranged perpendicular to the strike, and is particularly suitable for mining of thick and large ore bodies with low rock hardness. Background technique [0002] The upward horizontal layered filling method is a highly mobile and flexible mining method, which is suitable for the mining of ore bodies with medium stability and above, especially the mining of ore bodies with unstable surrounding rocks on the upper and lower walls. Therefore, it is widely used in underground mines in my country. Applications. [0003] The traditional upward and horizontal layered filling method mainly adopts the method of drilling and blasting, using rock drilling equipment to construct various types of blastholes, and filling the blastholes with detonators and explosives to blast the mines. Practice show...

AI Technical Summary

Problems solved by technology

Practice shows that the traditional drilling and blasting method mainly has the following disadvantages: (1) The safety risk is high, and the blasting vibration will cause irreversible damage to the surrounding rock mass, increasing the workload of stope support

(2) The various operation links of the drilling and blasting method are scattered and discontinuous, the production management is complicated, and the efficiency is low, 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 kind of mining method of layering and filling horizontally upwards with non-explosive mechanical rock breaking arranged perpendicular to the direction, aiming to solve the problems of poor safety, poor operation continuity and labor intensity in the traditional drilling and blasting mining of hard rock metal mines. problems such as large size and poor working environment, and at the same time, through innovations in engineering layout, the efficiency of cantilever roadheaders can be fully utilized
