Detailed description of the invention
As illustrated in the accompanying drawings from 1 to 3, a kind of horizontal method of mining by the way of filling of medium-length hole ore blast contiguous segmentation, these mining codes are carried out as steps described below:
(1) adopt and cut work arrangement:
First the lower wall at ore body arranges ramp, ramp is connected by the outer ore removal crosscut 3 of ramp connector 2 and each segmentation arteries and veins, ramp is the walking passageway of scraper and personnel, rock drilling ore removal lane 5 in arteries and veins is arranged in the middle part of ore body, mine chute 4 is arranged in ore body lower wall, it is connected with rock drilling ore removal lane 5 in arteries and veins by the outer ore removal crosscut of each segmentation arteries and veins, mine chute 4 bottom is connected with stage haulage way 1, Ore is transported to mine chute 4 by scraper, it is transported to vertical shaft, by shaft hoisting to earth's surface again by stage haulage way 1.
(2) stopping sequence:
In the horizontal direction, from panel, both wings retrusive advances continuously to centre, and vertical direction is exploited from stope lower to upper part segmentation.
(3) process for stoping:
First to fanhole(s) 8 on digging in rock drilling ore removal lane 5 in arteries and veins, big gun hole horizontal spacing 2m, bottom hole pitch 2.1m, blasthole diameter 90mm, adopting width is orebody thickness, every separate explosion 2-3 artillery salvo hole, fresh distinguished and admirable pass through ramp, ramp connector 2, the outer ore removal crosscut 3 of arteries and veins, after in arteries and veins, work surface is rinsed in rock drilling ore removal lane 5, dirty wind drains into return aircourse, stage casing by filling ventilation shaft 9, Ore is transported to mine chute 4 by scraper, treat that work advances about 25m towards centre, the goaf of this segmentation is carried out filling, lower goaf 9m uses cement: tailings is that the low-intensity cemented fill 7 of 1:8 carries out filling, top, goaf 1m uses cement: tailings is that the high intensity cemented fill 6 of 1:4 carries out filling.The like, until the ore body of this segmentation is produced and complete goes to higher slice.Higher slice rock drilling, ore removal are all to carry out in the high intensity obturator of lower leaf, the most effectively control the rate of dilution.
(4) structural parameters:
