Abstract
The utility model relates to a desorption meter for predicting the projection of coal and gas in coal mines. A K<1> value can be directly read on the underground running face of the coal mine, whether the projection danger of coal and gas exists can be judged by the k<1> value. The utility model is mainly composed of a water tank, a desorption tank and an underwater main scale. The utility model is characterized in convenient underground, simple and reliable operation, and low price, and the precision requirement of the utility model is satisfied.
Description
The utility model relates to a kind of to the outstanding desorption instrument of predicting of coal-mine gas.Can directly read K at the colliery mining face under mine
1Value is passed through K
1Value can judge whether coal and gas outburst danger.After the down-hole obtains data, do not use ground and calculate again, simplified acquisition K widely
1The program of value, its precision meets the demands.
At present, the colliery is considered desorb index K to be worth doing with coal borer at home
1Value weighs whether coal and gas outburst danger are arranged.In surveying instrument, can directly read K in the down-hole
1Value ATY-1 type electronics desorption instrument arranged, it can be considered coal borer after desorb discharges gas amount and be converted into electric weight to be worth doing, with solidifying K
1The single card microcomputer of value zooming program, thereby can directly calculate K
1Value.The weak point of this ATY-1 type electronics desorption instrument is that sensor and the single card microcomputer electrical measurement in the complex environment and zooming reliability under coal mine are relatively poor, the apparatus structure complexity, and maintenance technique requires high, costs an arm and a leg.
The purpose of this utility model provides a kind of easy to use under coal mine, can satisfy accuracy requirement, and low price can directly obtain K under coal mine
1Value comes the judgment task face whether the outburst prediction desorption instrument of coal and gas outburst danger is arranged.
The purpose of this utility model is achieved in that by the water column chi, and considering coal borer to be worth doing the gas burst size, to be converted into water column high and read, and is carved with on the water column chi to show K
1The scale of value, thus K can directly be read
1Value.By water tank, separate cucurbitula and the water column chi is formed this outburst prediction desorption instrument, can directly read K thereby be implemented under the coal mine
1Value judges whether the danger that coal and gas are outstanding at once.
Separating cucurbitula is made up of coal sample jar, desorb cover, desorb tank body, bleeder screw and O-ring seal.
Water tank is made up of water tank, water column pipe, zeroing nut, fastening nut, rubber washer.
The water column chi is by sealing bolt, O-ring seal, demonstration K
1Value scale, movable vernier scale are formed.
The utility model accompanying drawing
Accompanying drawing 1 outburst prediction desorption instrument front elevation
Accompanying drawing 2 outburst prediction desorption instrument vertical views
Accompanying drawing 3 outburst prediction desorption instrument ABCD cut-open views
Accompanying drawing 4 water column chis show K
1Value scale figure
The utility model embodiment
By single tube water column meter, consider coal borer to be worth doing the gas burst size and be converted into the water column height and read K
1The principle of value has been designed by water tank (3), has been separated the outburst prediction desorption instrument that cucurbitula (10), water column chi (6) are formed, thereby has realized under coal mine directly acquisition K
1Value.
Water tank (3) is made up of water tank (5), water column pipe (15), zeroing nut (1), fastening nut (2), rubber washer (14).Water column pipe (15) and water tank (5) weld together with weld seam (16).
Separating cucurbitula (10) is made up of coal sample jar (11), desorb cover (13), desorb tank body (12), bleeder screw (9) and O-ring seal (7).Separating cucurbitula (10) and water tank (5) welds with weld seam (16).
Water column chi (6) is by sealing bolt (8), O-ring seal (7), demonstration K
1Value scale (17), movable vernier scale (4) are formed.
Also can movable vernier scale (4).Can directly read K from water column chi (6)
1Value, movable vernier (4) is in order to make reading more accurate.K
1Value scale (17) is considered different gas burst sizes to be worth doing according to coal borer and is calculated and be depicted as, and its precision satisfies the requirement of colliery safety regulations and colliery protrusion-dispelling rules.
The utility model has the advantages that and directly to read K at the colliery mining face under mine1Be worth, its precision meets the requirements, and compares in ± 5% with the zooming value, and apparatus structure is simple, and is easy to carry, and easily maintenance is easy and simple to handle reliable, low price, the technical merit of comparatively suitable present China's coal mines.
