Description
Technical field
Methods and apparatus of the present invention relates to coal mine gas desorbing field, be specifically related to simple, automatically, the whole-process automatic test of desorption of mash gas process accurately and record.
Background technology
Gas is the accompaniment in coalification course, just have gas to occur as long as cutting coal, gas is one of key factor of harm mine safety production, is also one of disaster the most serious in colliery, 70% is above being caused by gas according to statistics in China's coal-mine production accident. Therefore, no matter it is mine main, New Built Mine or upgrading and extension plan, it is necessary to grasp the gas bearing capacity in coal seam and the regularity of distribution. Gas bearing capacity is the fundamental parameter administering gas, is also the important foundation foundation of Forecast of Gas Emission, gas outbursts Prediction, so coal seam gas-bearing capacity must be apparent from and recognize.
The commonly used desorption of mash gas method of current coal seam gas-bearing capacity measures, and the method, after the desorbing of down-hole, takes back laboratory desorbing. It is utilize coal sample tank samples of coal pulled, by exhaustor, the gas desorbed is guided to the buret equipped with liquid, directly record coal sample desorption of mash gas amount according to gas volume reading in buret, and record buret reading at interval of certain time, continuous-reading 2h or longer time, mensuration process needs professional and measures and reading, and number reading method is to read the scale on corresponding time correspondence buret, and make relative recording, in order to analyzing desorption of mash gas rule or inverse coal sample gas remaining quantity etc. The method is not only loaded down with trivial details, need personnel many during experiment, and limit sees that the scale on buret is read on time limit, not only cause temporal error, also because of artificial and scale is former thus results in error in reading, if each reading all exists error, then the coal sample desorption of mash gas speed measured and desorption quantity are by inaccurate, it is unfavorable for coal sampling desorption of mash gas rule, guide field gas control is lost reliable basis parameter; Simultaneously coal sample desorption of mash gas process more than 2 hours at least, reading and the recording process of data are all completed by experimenter, then can waste plenty of time and energy.
Summary of the invention
It is an object of the invention to overcome the weak point in existing technology, it is provided that one is rational in infrastructure simply, method is easy, measures accurately, and data visualization becomes to scheme directly perceivedization, the whole-process automatic test device of coal sample desorption of mash gas speed that result of use is good.

The coal sample whole-process automatic method of testing of desorption of mash gas speed of the present invention:
A, by fluid passage, liquid is installed in desorbing buret, put normal solution pipette afterwards, each pipeline is connected, close valve, debug balance, start intelligent object.
B, it is put into coal sample tank in the coal sample prepared, and is fixed on fixing seat, connect inducing QI syringe needle, open valve, the gas of coal sample solution sucking-off enters in the desorption chamber of desorbing buret by airway, correspondingly discharges the liquid in desorbing buret, utilizes liquid header to collect the liquid discharged.
The mass change of the liquid that liquid header is collected by c, electronic balance sends intelligent object to, and mass change is converted into change in volume automatically according to m=�� �� principle by intelligent object, i.e. the gas volume of coal sample desorbing.
D, as required, intelligent object could be arranged to record a secondary data different interval times, volume and time relationship according to coal sample desorption of mash gas, it is possible to the basic condition of whole-process automatic test and monitoring desorption of mash gas, and automatically derive coal sample desorption of mash gas speed and desorption quantity.
The invention has the beneficial effects as follows:
From the above mentioned, apparatus of the present invention are the desorption of mash gas adopting whole-process automatic test and monitoring to carry out coal sample, the liquid discharged in coal sample desorbing gas volume homographic solution pipette is collected by liquid header, the change of all-the-way tracking liquid quality, further according to m=�� �� principle, the liquid quality of change is converted into the volume of this liquid, and the liquid volume converted is in the corresponding time gas volume of coal sample desorbing, and these convert and record is all undertaken by intelligent object automatically. Whole coal sample desorption process achieves test automatically and monitoring, experimenter need not be sitting in reading and record before instrument for a long time, save substantial amounts of time and efforts, it also avoid the reading compareing desorbing buret scale artificial interval time simultaneously and cause time error above and on reading.
Thus apparatus of the present invention overcome the weak point in existing coal sample desorption of mash gas method, take the whole-process automatic test of coal sample desorption of mash gas and monitoring method. The method is easy, technically reliable, and certainty of measurement is high, and method is easily grasped, data visualization, becomes figure directly perceivedization, and does not need tester and follow the tracks of data acquisition for a long time and whole-process automatic test and record; This apparatus structure is simple, processing ease, and working efficiency is high, and cost is low, convenient test, has wide applicability and application value.
