Abstract

The invention discloses a track and trackless coupled bottom ore removal system. On the basis of a track development system which is formed, the configuration position of a trackless accurate mining system is raised by a subsection. A subsection inclined roadway is constructed from a track development tunnel to a first subsection, and the trackless accurate mining system is constructed in the subsection. Before stopping is conducted in a stope, a sublayer is firstly mined, an artificial false bottom is built by using reinforced concrete, then a triangular ore pillar at a hanging side of the near ore body is mined, and an ore gathering trench is built by using broken stones. The ore backstopped in the stope is loaded by trackless equipment, poured in a subsection jack shaft, delivered to an underground crushing station through a mine car in the track development tunnel, and finally hoisted to the ground through a skip bucket. The ore removal system is high in safety and ore removal capability and low in resource dilution.

Description

The bottom ore removal system that a kind of rail is coupled with trackless
Technical field
The present invention relates to a kind of bottom ore removal system, particularly relate to the bottom ore removal system that a kind of rail is coupled with trackless, be mainly applicable to the bottom ore removal system of stage open stope mining codes.
Technical background
After rail mining has formed rail Development system, introduce trackless equipment ore removal, solving trackless ore removal system becomes a mine difficult problem with being connected between rail ore removal system.If especially traditional stage open stope mining codes arrange Ji Kuang tunnel and ore removal route on the sustained height of rail development work, to greatly affect the production efficiency of trackless equipment in the mine car pouring rail development work into behind trackless equipment dress ore deposit, the connection problem solved between rail and trackless ore removal system necessitates.
Summary of the invention
Technical problem to be solved by this invention is to provide the bottom ore removal system that a kind of safety for stage open stope mining codes is high, ore removal ability is large, the poor damage of resource is little rail is coupled with trackless.
In order to solve the problems of the technologies described above, the bottom ore removal system that rail provided by the invention is coupled with trackless, step is as follows:
(1), on the basis of established rail Development system, trackless is adopted Barebone position and improve a segmentation.From the segmentation of rail development work construction segmentation ramp to the first, and construct in this segmentation segmentation drop shaft connection roadway and segmentation drop shaft, the ore removal route of driving slice drift and arrival ore body;
(2), before stope mining, first cut and adopt a layering, construct artificial false bottom with steel concrete; Cut the triangular stump adopted and close on and ore body coils again, build collection ore deposit moat ditch by laying bricks or stones with rubble;
(3), the ore of stope mining first loads through trackless equipment, pours in segmentation drop shaft, the car-haul then in rail development work to underground crusher station, finally by skip hoisting to earth's surface.
Adopt the bottom ore removal system that the rail of technique scheme is coupled with trackless, its beneficial effect is: can make full use of original trackless development engineering, avoid the problem resetting transportation route; The collection ore deposit moat ditch that reinforced concrete artificial bottom and rubble are built by laying bricks or stones, be not only lower stage casing cap pillar extraction and provide protection, and the once loss of ore is little, resource recycling rate is high.
In sum, the present invention is the bottom ore removal system that a kind of safety for stage open stope mining codes is high, ore removal ability is large, the poor damage of resource is little rail is coupled with trackless.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
See accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4 and accompanying drawing 5, the concrete use case of the bottom ore removal system that the rail that the present invention proposes is coupled with trackless is the bottom ore removal system of the stage open stope mining codes in certain ore deposit:
(1) nugget specification is 50 ~ 100m × 70m, and the long 50 ~ 100m of nugget, be highly 70m, be divided into 5 segmentations, except the first height of lift is 10m, all the other heights of lift are 15m.
(2) accurate cutting engineering is adopted: on the basis that there is rail development work 7, trackless is adopted Barebone position and improve a segmentation, to construct segmentation ramp 10 to the first segmentation from rail development work 7, at the first section construction segmentation drop shaft connection roadway 1 and segmentation drop shaft 9, then tunnel slice drift 2 and arrive the ore removal route 3 of ore body, tunneling the rock drilling gallery 12 of each segmentation at ore body both sides driving way shaft 15 and each segmentation of rock drilling connection roadway 16 to stope simultaneously.In stope central authorities near lower wall country rock place tunneling ventilation slot raise 11, simultaneously in ore body lower wall driving filling return air crosscut 13.
(3) artificial sill pillar: during stope mining, first cuts and adopts 3.8m ~ 4.2m, constructs the REINFORCED CONCRETE ARTIFICIAL false end 5 with steel concrete consolidated fill 1m; Cut the triangular stump adopted and close on and ore body coils again, build body 4 by laying bricks or stones with rubble and build artificial collection ore deposit moat ditch 6 by laying bricks or stones.
(4) driling explosion: first manually integrating ore deposit moat ditch 6 and rock drilling gallery 12 Drilling with the kerve medium-length hole of ventilation slot raise 11 as the scope of freedom, the parameter of kerve medium-length hole is: array pitch 1.0m, bottom hole pitch 1.0m.Next is scope of freedom Drilling fan shaped medium length hole with cutting groove, and the parameter of fan shaped medium length hole is: array pitch 1.2m, bottom hole pitch 2.0 ~ 2.4m.Explosion adopts modification ANFO explosives prill, and each every segment blast 3 ~ 5 is arranged, but upper segmentation should descend segmentation 1 ~ 2 to arrange in advance.
(5) ore drawing in stope: first trackless ore removal equipment at the ore of ore removal route 3 in-built manned Gong Ji ore deposit moat ditch 6, then poured in segmentation drop shaft 9; Mine car in rail development work 7 by the Ore Transportation in segmentation drop shaft 9 to underground crusher station, finally by skip hoisting to earth's surface
(6) stope filling: ore drawing in stope is complete, build filling counterfort 14 by laying bricks or stones in rock drilling connection roadway 16 and the junction of stope and the junction of ore removal route 3 and stope, casting resin carries out filling by goaf, 13 pairs, filling return air crosscut.
(7) Main Economic technical indicator: production capacity of mining field is 675t/d, ore loss ratio 6%, and ore dilution rate is 5%, adopts and cuts than being 9.57 standard m/kt (or 43.94m 3/ kt), rock drilling work efficiency is 35m/ machine-team, and every meter of big gun hole rock yield is 5.67m/t, and explosive specific charge is 0.38kg/t, and mining work efficiency is 71.89t/ work team; Mining cost (rock drilling, explosion, ore removal, filling) is 39.65 yuan/t.
The present invention emphasizes being coupled of trackless ore removal system and rail ore removal system, make original rail development engineering and follow-up trackless adopt accurate engineering to be effectively connected, achieving the ore removal of Stope safty, efficient, low cost and high strength, is the bottom ore removal system of stage open stope mining codes.
