[0002] The determination of coal seam gas content is an important means of evaluating coal mine safety. In the process of coal mining, direct determination of coal seam gas content is one of the commonly used methods. To ensure the accuracy of gas content determination, it is necessary to start from the coal seam gas content sampling method, analytical gas determination method, loss gas compensation method, residual gas determination method and coal seam gas content calculation method.

The S2 also includes comparative recognition of the correctness of the operation, identifying the operator's actions based on image recognition technology, and matching them with predefined operation steps, and issuing reminders when the operation is misplaced; the reminders include highlighting and voice reminders.

[0035] The gas content measuring equipment includes a coal sample tank, a gas desorption rate measuring instrument, an empty box barometer, a stopwatch, a thermometer, an exhaust pipe and a tool kit. The augmented reality device is used to identify the gas content measuring equipment through AI. The S2 also includes S21, when the gas content measuring equipment is insufficient, a missing reminder is issued. Figure 2 As shown, the gas content determination includes:

[0036] S22, input the basic information of the coal sample through voice recognition; the basic information of the coal sample includes the coal sample number, sampling date, sampling location, sampling coordinates, depth of coal encountered by the borehole, sampling depth, sampling start time, sampling end time, coal sample filling time, coal sample filling end time, start desorption time, geological profile of the sampling location and coal quality profile. Voice recognition is used for input, wherein the sampling start time, sampling end time, coal sample filling time, coal sample filling end time and start desorption time are automatically recognized by the keywords "sampling start", "sampling end", "coal sample filling", "coal sample filling end" and "start desorption" in the operation guidance three-dimensional virtual animation and immediately obtain the time record at this moment, and automatically obtain the virtual and real superposition picture of the augmented reality device at this moment to retain evidence.

When it is automatically determined that the underground natural desorption is over, a prompt "Please close the coal sample tank" is given to end the underground natural gas desorption process, and the gas loss W1 is calculated; the calculation method of W1 is as follows:

[0038] Assuming the loss time is t0, desorption starts at 3 minutes, the desorption amount at 4 minutes is Q11, the desorption amount at 5 minutes is Q12, the desorption amount at 6 minutes is Q13, ..., Q1n, then:

[0039]

[0040] Where a represents a coefficient of an exponential equation, x is the unknown number, and y = a*x i , a and i are constants obtained by fitting. For example, if a=5 and i=3 are obtained by fitting, then when x is 3, y=5*3 3 By fitting the unknown parameters of the above multiple equations, the gas loss amount W1 is obtained, and the underground natural gas desorption amount W21 = Q1n.

[0041] S24, determine the natural desorption gas content on the ground; after sending the coal sample to the laboratory, conduct a leak test, and proceed to the next step when the seal meets the requirements, otherwise it will prompt that the sample is a waste sample. The leak test includes: sinking the coal sample tank into clean water, observing whether there are bubbles within 10 minutes, if there are bubbles, it means there is a leak, otherwise there is no leak. Then prompt to connect the coal sample tube outlet nozzle to the ground gas desorption measuring tube, turn on the backlight tube of the ground desorption device, operate the glass tube operating handle to the water absorption and exhaust gear, press the vacuum pump start button to exhaust and absorb water, stop when the liquid level reaches the target position, adjust the desorption tube operating handle to isolate the vacuum pump from being connected, and make the desorption tube in a sealed state. After confirming that the debugging is intact, read and take a photo to record the initial measurement liquid level value Q21, and then prompt to open the coal sample tube valve until the liquid level no longer drops, and record the measured liquid level value Q22; the ground natural desorption gas content W22 = Q22-Q21.

[0042] S25, determine the crushing gas content of the coal sample; specifically, give voice prompts for each operation step, weigh the coal sample and take photos to record the weighing picture, identify the value of the electronic balance and record the weight of the coal sample, weigh the coal sample of equal weight of 100g, take photos and record the weighing pictures of two samples, identify the value of the electronic balance and record the weight of the coal sample; put the weighed first coal sample into the cylinder body, cover it with a lid with a sealing ring, and press it tightly to seal it, then take photos and record the initial measuring cylinder liquid level value Q31, set the pulverizer timer to 3 to 5 minutes, and observe the measuring cylinder liquid level value Q32 at the end of the operation; the crushing gas content of the first coal sample W31=Q32-Q31, repeat the measurement of the second sample, and the crushing gas content of each second sample is W32; calculate the crushing gas content of the coal sample W3=(W31+W32) / 2.

[0044] S27, the residual gas content is calculated based on the Langmuir equation; the Langmuir equation is:

[0045]

[0046] Where, q is the gas content adsorbed at pressure p, q m is the maximum adsorption capacity (saturated adsorption capacity), that is, the maximum amount that can be adsorbed under infinite high pressure; p is the pressure of the adsorbate; p0 is a constant related to the surface characteristics of the adsorbent and the properties of the adsorbate, representing the half-saturation pressure, that is, the pressure when the adsorption capacity reaches half of the maximum adsorption capacity, and the residual gas content is the total gas content minus the adsorbed gas content.

[0047] S28, the coal seam gas content is calculated based on the natural gas desorption amount underground, the natural desorption gas content on the ground, the gas content of coal sample crushing and the residual gas content. The calculation formula is: W=W1+W2+W3+Wc.

[0048] S3, automatically records the process data of gas content measurement through augmented reality equipment, and saves the process data to the server in real time using 5G network technology. The process data includes video, picture, sound and gesture information data.
