Description

A kind of pick block construction in layer method of high Large chamber

Technical field

The invention belongs to mining engineering technical field of construction, construction in layer method is built in the pick of especially a kind of high Large chamber.

Background technique

Due to continuous mature and equipment the continuous development of mining technique, high Large chamber more and more appears in ground In lower mine, and the driving and supporting construction of high Large chamber are always the key points and difficulties of mine capital construction construction, and traditional is tall and big Chamber driving and masonry construction generally uses tunneling boring construction method, layered construction method and leads three kinds of methods of cave construction method, however these three sides Method all has some limitations.Or influenced by section, difficulty of construction of breaking is bigger and construction efficiency is lower;Or by sequence of construction shadow It is difficult to ring muck, inconvenience of slagging tap, safety coefficient is low, or is influenced by chamber specification and wall rock condition, problem poor for applicability. How efficiently, safety, the high construction in large chambers of completion for guaranteeing quality are always the project of mine construction research.

Summary of the invention

The technical problem to be solved in the present invention is to provide one kind conveniently, safely, efficiently the pick of high Large chamber is built layering and applied Work method.

In order to solve the above technical problems, method and step adopted by the present invention is:A, it constructs in the position of chamber opening To inclined gallery at the top of through chamber tail end, in the gallery of slagging tap of the through chamber tail end of side construction of chamber opening;In chamber To the drop shaft of slagging tap of inclined gallery and gallery of slagging tap in the position construction perforation of rear end first layer;

B, first layer is tunneled to inclined gallery on passing through, the supporting in driving, drop shaft and gallery of slagging tap are slagged tap by slagging tap;

C, after first layer construction, drop shaft of slagging tap expands side to inclined gallery side until to inclined gallery in the perforation of the second layered position upwards With gallery of slagging tap;

D, to the second layering of inclined gallery driving on passing through, the supporting in driving, by slagging tap, drop shaft and gallery of slagging tap are slagged tap;

E, the construction method of subsequent hierarchy is identical as step C, D;Until tunneling to minimum layering.

In step A of the present invention, gallery of slagging tap is located at the chamber opening position n-1/n inward, and n indicates Chamber Construction layering Number.

In step E of the present invention, driving is to when minimum layering, primary pick to chamber bottom plate, directly to slag tap gallery into Row expands side, until completing whole Chamber Constructions.

Meet mucking machine to inclined gallery on of the present invention to pass through, it is current that gallery of slagging tap meets transporting equipment.

Generated beneficial effect is by adopting the above technical scheme:The present invention on to inclined gallery, slag tap gallery and go out Slag drop shaft makes entire high Large chamber form a set of slag-tapping system up and down;It, can be by slagging tap when constructing each layering Drop shaft and gallery of slagging tap are slagged tap, and the driving and masonry construction of construction in layer Large chamber from top to bottom is realized;It is simple with the mode of slagging tap, it applies The features such as work is safe and reliable and high-efficient is suitable for all kinds of high construction in large chambers.

Detailed description of the invention

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

Fig. 1 is structural schematic diagram of the invention;

Fig. 2 is sectional schematic diagram of the invention.

In figure:1- chamber, 2- is upper to inclined gallery, and 3- slags tap gallery, and 4- slags tap drop shaft, 5- first layer, 6- second Layering, the layering of 7- third.

Specific embodiment

The pick of this high Large chamber builds construction in layer method according to planned design, and from top to bottom a point n-layer is constructed;In construction chamber When first construction it is upper to inclined gallery, slag tap gallery and drop shaft of slagging tap, make entirely high Large chamber form a set of slag-tapping system up and down, Then construction in layer can be carried out to high Large chamber.

Shown in Fig. 1, Fig. 2, with reference to the accompanying drawing to divide tri-level construction to be illustrated this construction method, the specific steps are: (1)To inclined gallery 2 in the middle position construction of high 1 open end bottom of Large chamber, construct obliquely from the bottom of 1 open end of chamber Go directly the top of high 1 tail end of Large chamber, the open end of oblique perforation chamber 1 and tail end, size as far as possible with the tunnel ruler that connects It is very little identical, it is current to meet mucking machine.It slags tap gallery 3, slags tap flat to the construction of the side of inclined gallery on 1 open end bottom of chamber abuts Lane 3 penetrates through the bottom position of chamber 1 open end and tail end, and cross dimensions should meet transporting equipment and pass through, and pick to chamber 1 designs tail End.In 1 open end of chamber n-1/n inward(N indicates Chamber Construction hierarchy number)Position construction is slagged tap drop shaft 4, by to inclined gallery 2 and Gallery 3 of slagging tap perforation;Shown in Fig. 2, drop shaft 4 of slagging tap is located at the position of first layer 5 on to the connectivity part of inclined gallery 2.In this way, whole A high Large chamber forms a set of slag-tapping system up and down, then can carry out the high Large chamber of construction in layer.

(2)Chamber arch is tunneled to the left and right sides respectively to inclined gallery 2 on, the supporting in driving, on two mucking machines Lower parallel loader, by slagging tap, drop shaft 4 and gallery 3 of slagging tap are slagged tap, until the construction of first layer 5 is completed.

(3)Due to slag tap drop shaft 4 on to inclined gallery 2 second layering 6 bottom plate at penetrate through respectively, that is, slag tap drop shaft 4 with On 6 be not connected to inclined gallery 2 in the second layering, can not be slagged tap by drop shaft 4 of slagging tap, the drop shaft 4 that will need to first slag tap is passed through on to inclined gallery 2 Logical, Specific construction mode is to slag tap drop shaft 4 upwards to the side of inclined gallery 2 expansion side until the two perforation.Then it is applied with first layer 5 Work is identical, the second layering 6 of driving, and in Zhao Bang, linked network beats anchor pole gunite in tunneling process.

(4)Start third layering 7 of constructing, the primary pick of 7 construction of third layering to 1 bottom of chamber after second layering, 6 construction Plate directly can carry out expansion side to gallery 3 of slagging tap, until completing whole Chamber Constructions.

(5)If point more numbers of plies are constructed:The form of construction work of the intermediate number of plies uses step(3)The construction party of second layering Formula;For driving to when minimum layering, use is above-mentioned(4)The mode of middle third layering, primary pick are directly flat to slagging tap to chamber bottom plate Lane carries out expansion side, until completing whole Chamber Constructions.
