Embodiment Construction

[0026] The technical solutions in the embodiments of the present invention will be further described below in conjunction with the accompanying drawings of the present invention and specific embodiments, and the described embodiments are only some of the embodiments of the present invention, not all of them.

[0027] Such as Figure 1 to Figure 3 As shown, a lead-zinc deposit has high ore grade, the mining depth is 1000m from the surface, the ore body structure is broken, the fault fracture zone is developed, the stability is poor, and the stability of the surrounding rock is good. In order to meet the production task, a large-diameter deep hole side Go back to the ore mining method of collapsing. The structural parameters of the deep high-grade ore blocks are: the ore blocks are arranged vertically, the length of the ore body is generally 45m in thickness, 50m in height, and 6m in width. , after the mining is completed, the goaf 1 is filled with cemented filling materials wi...

Abstract

The invention discloses a recovery method of a high-grade ore body in a deep collapse area, which is characterized in that: a three-dimensional laser void area detection system is used to detect the upper void area of ​​the collapse area, and a high-strength grouting material is used to grout the ore body in the collapse area , the upper empty area is filled and maintained with low-strength and high-strength filling materials, and the mining and cutting work is arranged outside the collapsed area. The flat bottom structure is adopted. During the mining work, combined with the detection data, the fan-shaped medium-deep holes are accurately arranged, and remote control is used. The scraper goes out of the mine and fills the empty area after mining. The invention is especially suitable for the recovery of deep high-grade collapsed ore bodies, and has the characteristics of high mining efficiency, safe operation, high recovery rate of high-grade collapsed ore bodies, and the like.

Description

technical field [0001] The invention relates to a method for recovering an underground collapsed ore body, in particular to a method for recovering a high-grade collapsed ore body suitable for deep underground mining of metal mines. Background technique [0002] With the development of the national economy, the consumption of metal mineral resources has risen sharply, the efficiency of underground mining of metal mines has been greatly improved, and the requirements for the output of single stope are getting higher and higher. Such as figure 1 , now the stope structural parameters increase, the mining depth increases, the exposed area increases and the filling work is not timely. The ore body is also affected by factors such as ore rock structure, blasting vibration, stope structure parameters and mining sequence during mining. Deep stope The instability of ore blocks adjacent to the goaf appeared, forming a collapsed area. The mining safety and technical conditions of the...
