Description

A kind of for the lower servicing unit ventilated to admission passage filling mining

Technical field

The utility model belongs to apparatus for work field under ore deposit, particularly relates to a kind of for the lower servicing unit ventilated to admission passage filling mining.

Background technology

The mining methods of metallic ore underground mining are varied, but because of the orebody occurrence that metal ore itself has, the complexity of orebody shape is large, and metallic ore rock is hard, mechanization degree is low waits restrictive condition, makes the aeration technology in metallic ore mining process also have very large development room for improvement.

The lower draft type generally adopted to admission passage filling method that existing route is arranged along orebody trend is, People's Bank of China's vent (-escape) raise is forced air intake from bottom to top, new wind turns back after entering route work plane again and is drawn to top return airway along the pulse through filling returnairshaft, until main filling-air return system.

At least there is following shortcoming in above-mentioned existing ventilation system: new wind can through over packing returnairshaft after entering exploitation route, take away so most fresh wind does not also have arrival route work plane to be just filled with returnairshaft, simultaneously, part enter work plane wash away after weary wind turn back in route and to mix with new wind, cause the fresh wind of work plane to run off in a large number, distinguished and admirable of poor quality, route drafting efficiency is low, cost is high, can affect the exploitation construction of route work plane when situation is serious greatly.

Utility model content

The purpose of this utility model is to provide a kind of for the lower servicing unit ventilated to admission passage filling mining, is intended to solve or improve the lower problem to the ventilation drawback in admission passage filling mining process that metal mining route is arranged along orebody trend.

The utility model is achieved in that a kind of for the lower servicing unit ventilated to admission passage filling mining, comprises air duct, plugging plate, anchor pole and hook; Described air duct is the skeleton scalable rigidity air duct of the annulus of built-in flexible bar, the outer of described air duct end mounting strap metal, with return air inlet in the middle of described plugging plate; Wherein,

Described air duct is directly docked with the return air inlet in the middle of plugging plate by metal outer and forms return air path, described plugging plate is fixed on filling returnairshaft well head lower end by anchor pole, described air duct controls length by expansion link and to advance with route and constantly extend, under being suspended to by air duct and being covered obturation by hook in route.

Compared to the shortcoming and defect of prior art, the utility model has following beneficial effect: the utility model structure simplify, easy to operate, use flexibly, cost is low, can improve largely metal mining route along orebody trend arrange lower to the ventilation drawback in admission passage filling mining process.

Detailed description of the invention

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

As illustrated in fig. 1 and 2, wherein, Fig. 1 is the using state schematic diagram of the utility model for the lower servicing unit to admission passage filling mining ventilation; Fig. 2 is that the utility model is for the lower structural representation to air duct in the servicing unit of admission passage filling mining ventilation; Fig. 3 is the structural representation of the skeleton scalable rigidity air duct of annulus in the utility model.

For the lower servicing unit ventilated to admission passage filling mining, comprise air duct 7, plugging plate 5, anchor pole 6 and hook 9; Described air duct 7 is the skeleton scalable rigidity air duct of annulus of built-in flexible bar, the outer of described air duct 7 end mounting strap metal, with return air inlet in the middle of described plugging plate 5; Wherein,

Described air duct 7 forms return air path by metal outer with nested fastening of return air inlet in the middle of plugging plate 5, described plugging plate 5 is fixed on filling returnairshaft 2 well head lower end by anchor pole 9, described air duct 7 controls length by expansion link and to advance with route and constantly extend, and to be suspended in route by air duct 7 to cover obturation 10 times by linking up with 9.

In the utility model embodiment, metal mining route along orebody trend arrange lower to access back-filling method, as shown in Figure 1, comprise under ore deposit top along the pulse return airway 1, filling returnairshaft 2, People's Bank of China's vent (-escape) raise 3, Mining entrance 4, unmind ore body 8, on cover obturation 10.

In actual application of the present utility model, new wind enters Mining entrance 4 through People's Bank of China's vent (-escape) raise 3 part, part directly enters top along the pulse in return airway 1, plugging plate 5 is fixed on filling returnairshaft 2 lower end through anchor pole 6, and the skeleton scalable rigidity air duct 7 of annulus is suspended to covers obturation 10 times through linking up with 9.Be suspended to by hook 6 when air duct 3 extends with route propelling and cover obturation 10 times.

In utility model embodiment, more specifically, the improvements that the skeleton scalable rigidity air duct 7 of annulus is applicable to the utility model device are in design metal outer 71, air duct end, make air duct can pass return air inlet from bottom to top, air duct 7 end is nested in the middle return air inlet of plugging plate 5, air duct 7 skeleton is its inside annulus 72 at a certain distance, in route, air duct is fixed by hook suspention annulus, controls air duct length make it advance progressively to extend with route and take weary wind in time away by controlling expansion link in air duct.

In actual application of the present utility model, the secondary ventilation device that plugging plate 5 is combined with air duct 7, when filling returnairshaft 2 realizes returnairshaft function, on the one hand, can shutoff filling returnairshaft 2, prevent from newly distinguished and admirablely being taken away in a large number when filling returnairshaft 2 lower end import, on the other hand, telescopic air duct 2 advances with route and progressively extends, the weary wind timely in suction air duct that can will wash away work plane, then enters top return airway 1 along the pulse through filling returnairshaft 2.Adopt to route under this, when filling returnairshaft 2 realizes filling material feeding function, plugging plate 5 and air duct 7 have been pulled down.This device can installing/dismounting simple and easy, easy to operate, the high efficiency return air to access back-filling method can be realized down, namely save ventilation cost, improve again the working environment of route work plane.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
