4. a kind of not coal containing methane gas imbibition method for testing height, it is characterised in that be free of using one kind as claimed in claim 3
Bottle coal imbibition high measure device, is carried out in accordance with the following steps：
It is prepared by the first step, moulded coal：
The fresh coal sample fetched once is crushed with pulverizer, then screened, filtering out coal sample particle diameter respectively is
Below 0.25mm and 0.25mm ~ 0.5mm coal sample；
The coal sample that the coal sample and particle diameter that the particle diameter for weighing certain mass respectively is below 0.25mm are 0.25mm ~ 0.5mm, according to
2:1 ratio is uniformly mixed, and is added 20% distilled water, is sufficiently stirred；
Moistening coal sample after being sufficiently stirred is added in moulded coal mould, under constant pressure, voltage stabilizing 20min is manufactured
Moulded coal；
The moulded coal made is placed in drying box and dried, and it is 105 DEG C to set drying box, every 0.5h test atures of coal
Amount, until briquet quality no longer changes, so as to obtain dry moulded coal（1）；
Second step, prepare water-sensitive colored indicator：
Carboxymethyl cellulose, calcium carbonate, titanium dioxide, cobaltous sulfate and cobalt thiocyanate are dissolved in water, according to 1:2:5:6:13:32
Ratio prepares water-sensitive colored indicator, comprises the following steps that：
Carboxymethyl cellulose, calcium carbonate, titanium dioxide, cobaltous sulfate and the cobalt thiocyanate of certain mass are weighed in proportion；
Cobaltous sulfate and cobalt thiocyanate are dissolved in water；
Add carboxymethyl cellulose；
Add titanium dioxide and calcium carbonate；
It is sufficiently stirred obtained water-sensitive colored indicator；
3rd step, smear water-sensitive colored indicator：
The water-sensitive colored indicator prepared is applied to dried moulded coal outer wall（3）On, water-sensitive colored indicator forms banded regions
Domain（2）, the moulded coal for scribbling water-sensitive colored indicator is put into drying box and dried, until the color of water-sensitive colored indicator is changed into ash
Color and mass conservation, are then placed in drier and cool down；
4th step, it is set with transparent heat-shrink tube：
By the transparent heat-shrink tube with moulded coal equal length after drying（5）It is enclosed on the moulded coal for scribbling water-sensitive colored indicator（4）On, and put
Put and heated in drying box, transparent heat-shrink tube（5）In the environment of higher than 70 DEG C, it may occur that shrink, until moulded coal is tightly wrapped up,
So as to form the moulded coal for being cased with transparent heat-shrink tube（6）, it is then placed in drier and cools down；
5th step, paste graduated scale：
It is being cased with transparent heat-shrink tube moulded coal（6）Outer wall on paste and the papery millimeter graduated scale of moulded coal equal length（7）, papery milli
Rice graduated scale（7）It is pasted onto the belt-like zone of water-sensitive colored indicator formation（2）The edge of side, papery millimeter graduated scale（7）
" 0 " scale and be cased with the moulded coal of heat-shrink tube（6）Bottom overlaps, so as to which the experiment moulded coal after specially treated be made（8）；
6th step, uiform section tank add water：
Open the first valve (13）, by certain thickness h1Sponge（11）It is placed on uiform section tank（10）In, and in uiform section water
Groove（10）Middle addition water（9）, until having water from being highly h apart from uiform section bottom of gullet2The first pvc pipe（14）Middle spilling；
7th step, adjust the water level in tank：
In low tank（16）And water head tank（19）The middle water for adding equivalent, wherein low tank（16）And water head tank（19）
Height of water level be h2-h1Several times；
8th step, device water circulation：
The experiment moulded coal after specially treated（8）It is placed on uiform section tank（10）On middle sponge（11）, while open the
Two valves（21）And suction pump（17）Switch, water head tank（19）In water constantly to uiform section tank（10）Middle supply, when
Uiform section tank（10）In water level exceed its left survey intermediate openings（12）When, water is from uiform section tank（10）Intermediate openings
Overflow and enter low tank（16）In, low tank（16）In water by pumped of drawing water, and feed water head tank（19）, shape
Into water circulation；
9th step, data record：
Not coal containing methane gas imbibition in the presence of the saturation water of bottom, at regular intervals ti（i=1、2、3、…、n）, it is real that water is met in observation
Shi Xianse（Display color is white, blueness or pink）Height value Hi（i=1、2、3、…、n）, as not coal containing methane gas
Imbibition height.
