Abstract

The invention relates to a mining preparation method capable of being combined with multiple mining methods. According to the mining preparation method, firstly, every two stopes share one ore drawing transportation transverse drift and one ore drawing draw shaft; secondly, every two stopes share a part of a stope linked roadway; thirdly, a main transportation roadway and segmented roadways are closer to ore, and engineering length of the transportation roadway and the segmented roadways is reduced; fourthly, under the condition that the total number of the stopes is not changed, the conjugate type mining preparation method has the advantages that cooperative win-win that one plus one is greater than two in the adjacent stopes is realized, the number of mining preparation systems is greatly reduced, the mining and development ratio is greatly reduced, the mining preparation period is greatly shortened and remarkable economic benefit and time benefit are achieved through pairwise grouping of the adjacent stopes and sharing of the ore drawing transverse drift, a raise and part of linked roadways; fifthly, the mining preparation method can be combined with multiple mining methods such as an upward cut-and-fill mining method and the like and has broad application prospect.

Description

Conjugation-type adopts accurate method

Technical field

The present invention relates to a kind of can combine with multiple mining methods adopt accurate method.Adopt the method adopt Barebone, can save nearly one times adopt accurate engineering quantity, improve to adopt and cut ratio.

Background technology

What stope independently adopted complete set adopts accurate engineering system, is that metal, the general tradition just adopted of non-metal mine mining adopt accurate method both at home and abroad at present.This traditional concrete engineering adopting accurate method is arranged, to determine according to concrete mining methods, but no matter adopt which kind of mining methods, its common trait of adopting Barebone is: each stope has the independently engineering such as ore removal Chuan Mai tunnel, independently drop shaft and ventilation drainage sump, independently Cai Zhunlian lane.For Upward drift, the method is on the basis of developing, by bottom main haulage roadway construction ore removal Chuan Mai tunnel, to construct each segmentation lane by adopting accurate ramp, by segmentation lane construct each stope join lane arrive ore body, again by main haulage roadway construct drop shaft, ventilation drainage sump and with stope UNICOM, formed and a set ofly adopt Barebone, and often Barebone adopted by cover is only the service of a nugget stope.

The shortcoming that tradition adopts accurate method is: adopt that accurate engineering quantity is many, engineering quantity is large, adopt accurate long in time limit, waste a large amount of financial resources, material resources, manpower; When production target is higher, easily a large amount of adopts accurate engineering because completing, and enough standby rooms of digging up mine cannot be provided, cause explored ore reserve unbalance, and then production capacity is reduced.

Summary of the invention

Problem to be solved by this invention:

There is provided a kind of can combine with multiple mining methods adopt accurate method, make every two stopes save an ore removal Chuan Mai tunnel, drop shaft, part connection lane engineering.The method can reduce to adopt accurate engineering quantity, reduces mining time, improves to adopt and cuts ratio, improves mining benefit.

Technical scheme provided by the invention is:

A kind of conjugation-type adopts accurate method, and wherein " conjugation " means a pair that matches according to certain rules.For upward horizon access back-filling method, it is characterized in that adopting standard containing following steps:

(1), be nugget stope by stage casing ore body division, and press 1# and 2#, 3# and 4#, 5# and 6# ... be numbered grouping;

(2), by the large lane of bottom level haulage, the ore removal transport Chuan Mai tunnel that stope is often organized in construction arrives ore body;

(3), arrive by a segmentation roadway construction " Y-shaped conjugation joins lane " ore body often organizing stope respectively;

(4), by main haulage roadway construct drop shaft, ventilation drainage sump, wherein drop shaft carries out brushing dilatation, and wherein ventilation drainage sump and stage casing, top ore removal wear arteries and veins roadway linking, forms ventilation circuit;

(5), by stope join lane construction drop shaft passage, ventilation drainage sump passage, form ore removal ability and ventilation discharging capacity;

(6), wearing arteries and veins base plate is left foundation to 7 meters, its top ore body, more than 7 meters formal stoping operations by a segmentation " Y " font joins lane.

Benefit of the present invention is:

1), by N number of stope, adopt Barebone with N/2 cover and carry out adopting standard, engineering quantity saves half, saves and adopts accurate investment in a large number;

2), by N number of stope, adopt Barebone with N/2 cover and carry out adopting standard, the duration saves half, greatly reduces mining time;

3), the invention enables transportation roadway, segmentation lane from ore body more close to, save transportation roadway, segmentation connection lane engineering length;

4), on technological layer, the present invention can combine with multiple mining methods, greatly improves adopting of mining methods and cuts ratio;

5), on construction investment, technical scheme provided by the invention improves the investment yield of mining, shortens the investment payback time of mining, has won economic benefit and Saving in time costs.

Accompanying drawing explanation

Fig. 1 is that the present invention indulges perspective view;

Fig. 2 is sectional drawing of the present invention;

Fig. 3 is plan view of the present invention;

Note: draw for conjugation-type Upward drift in figure.

Detailed description of the invention: further describe the present invention below in conjunction with accompanying drawing.As shown in Figure 1, to adopt the technique of Barebone engineering as follows for conjugation-type:

The first, wear arteries and veins 2 and arrive ore body by main haulage roadway 1 ore removal of constructing, construction drop shaft passage, and upwards to be constructed drop shaft 3 by drop shaft passage, construction ventilation drainage sump passage, and by ventilation drainage sump passage construction ventilation drainage sump 4,5, wear 14 through with stage casing, top ore removal;

The second, share connection lane 7 by segmentation lane construction " Y " font stope, at " Y " font crosspoint place, separately construction 1# stope joins lane 8 and 2# stope connection lane 9 respectively, and in good time by connection lane construction drop shaft passage and ventilation drainage sump passage;

Three, bottom ore is worn arteries and veins base plate and be left foundation to 7 meters, its top ore body, more than 7 meters formal stoping operations by a segmentation " Y " font joins lane.

Application conjugation-type mining methods carry out adopting accurate work arrangement, compared with adopting accurate method, greatly reduce nugget and adopt accurate engineering quantity with tradition, greatly reduce to adopt and are cut into this, considerably reduce to adopt and cut ratio, have obvious economic benefit and Saving in time costs.
