Technical Field
[0001] This disclosure relates to the field of explosive performance evaluation equipment, and in particular to a device, system, and method for evaluating the heat resistance of thermal explosives. Background Technology
[0002] Currently, coal, as my country's primary energy source and industrial raw material, occupies a vital position in the national economy. Due to the long-term, continuous spontaneous combustion of coal, the temperature of the rock strata covering the coal seams is extremely high, ranging from 60-150℃ to as high as 500℃. Blasting in such rock strata is classified as high-temperature blasting. Blasting and stripping in high-temperature rock masses places demands on the heat resistance of the blasting materials. Since explosives generally have a specific operating temperature range, excessively high or low temperatures make blasting operations extremely difficult. The presence of these spontaneously combusting zones also poses significant safety hazards to subsequent mining operations.
[0003] The heat resistance of explosives is essentially a matter of thermal decomposition. Explosives that decompose easily when heated have poor heat resistance; explosives that do not decompose easily when heated have good heat resistance.

[0046] Example 3: Based on the above embodiments, this embodiment provides a system for evaluating the heat resistance of thermal explosives.
[0047] The thermal explosive heat resistance evaluation system provided in this embodiment includes: The explosive heat resistance evaluation device as described in the foregoing embodiments; The user interaction module is communicatively connected to the control device and is used to receive the expected environmental parameters and / or the duration of constant temperature input by the user; wherein, the expected environmental parameters include the expected temperature and / or the expected humidity. The control device is communicatively connected to the explosive heat resistance evaluation device, the user interaction module, and the display device, and is configured to: generate environmental parameter adjustment instructions for adjusting the internal environmental parameters of the constant temperature drying oven based on the expected environmental parameters and / or constant temperature duration input by the user; control the temperature acquisition module to acquire the temperature of each sample container, generate a temperature-time curve based on the temperature, and send the temperature-time curve to the display device for display; wherein, the environmental parameters are the environmental parameters inside the containment cavity of the constant temperature drying oven; A display device is used to display the temperature-time curve and / or the temperature of each of the sample containers.
[0048] In some optional embodiments, where the constant temperature drying oven has multiple independent cavities, the user interaction module includes: A cavity determination unit is used to determine a target cavity from the plurality of independent cavities in response to a user's selection operation; The input unit is used to receive the expected environmental parameters and / or temperature holding time set by the user for the target cavity. When the constant temperature drying oven has multiple independent cavities, a cavity can be selected first, and then the corresponding expected environmental parameters and / or temperature holding time can be set for the selected cavity. Expected environmental parameters include expected temperature and / or expected humidity, and the temperature holding time is the duration for which the cavity is maintained under the expected temperature and / or expected humidity conditions.
[0049] In some optional embodiments, the control device is further configured to generate environmental parameter adjustment commands for adjusting the internal environmental parameters of the target cavity based on the expected environmental parameters and / or the isothermal duration. Environmental parameter adjustment commands can be generated separately for each cavity, thereby controlling incompatible interference between cavities and allowing them to operate independently.
[0050] Specifically, the display device can display the internal environmental parameters of each cavity, as well as the temperature-time curves corresponding to each sample container.
[0051] Example 4: Based on the above embodiments, this application provides a specific example.
[0052] refer to Figure 2 The thermal explosive heat resistance evaluation system provided in this embodiment includes: The constant temperature drying oven 1 is used to heat sand and explosive samples. It can heat sand and explosive samples to a predetermined temperature and maintain this temperature for a long time with an accuracy of ±1℃. The MR8741 storage recorder 2 uses a dedicated DVM unit MR8990, which is connected to it via a K-type thermocouple 5. It can perform high-precision, high-resolution measurements of minute changes in sensor output or battery voltage changes, and can also measure sample temperature in real time. 3. Iron buckets, used to hold sand and 4. Small steel cylinders; Small steel cylinder 4, with an inner diameter of 15mm, a height of 100mm, and a wall thickness of 4mm, is used to hold explosive samples; Type K thermocouple 5 is suitable for temperatures not less than 300℃. Type K thermocouple 5 features high sensitivity, durability, and accurate data. The control device (not shown in the figure) is communicatively connected to the explosive heat resistance evaluation device, the user interaction module, and the display device, and is configured to: generate environmental parameter adjustment instructions for adjusting the internal environmental parameters of the constant temperature drying oven 1 based on the expected environmental parameters and / or constant temperature duration input by the user; control the temperature acquisition module to acquire the temperature of each sample container, generate a temperature-time curve based on the temperature, and send the temperature-time curve to the display device for display; wherein, the environmental parameters are the environmental parameters inside the accommodating cavity of the constant temperature drying oven 1.
[0053] Specifically, the small steel cylinder 4 was placed in a sand bath, and the cylinder 4, buried in the sand, was heated using a constant-temperature drying oven 1 to simulate a high-temperature blast hole. The test temperature range was controlled within any temperature between 50℃ and 250℃. The temperature sensing end of a type K thermocouple 5 was attached to the outer wall of the small steel cylinder 4, and the other end was connected to an MR8741 storage recorder 2 to record the temperature changes of the explosive sample. The mass of the explosive sample during the test was 10 grams.
[0054] The MR8741 storage recorder 2 is connected to the display 6 via the data cable 7, and the relevant data is displayed on the display 6.
[0055] The specific operating procedures include: Step 1: Open the constant temperature drying oven 1 and heat the sand in the iron drum 3; Step 2: When the sand temperature reaches the predetermined temperature, weigh the explosive sample; its mass is 10 grams. Two sets of explosive samples were weighed. Sample 1 consisted of 10 grams of pure ammonium nitrate (ANF) explosive, with a mass ratio of porous granular ammonium nitrate to diesel oil of 94:6. Sample 2 consisted of 10 grams of ANF explosive with added heat-resistant inhibitors. Both samples were weighed simultaneously and used immediately. The explosives were one or more combinations of emulsion explosives and ANF explosives. The type of explosive was not limited to a single civilian explosive; by adding other types of explosives and additives, the application scenarios for testing could be expanded.
[0056] Step 3: Place the explosive sample into small steel cylinder 4 and seal the opening of small steel cylinder 4 with sand; The weighed explosive samples were placed into the bottom of a single-opening small steel cylinder 4, sand was filled to the opening, and the opening was sealed with heat-resistant tape.
[0057] Step 4: Use heat-resistant tape to attach the temperature sensing end of the K-type thermocouple 5 to the outer wall of the small steel cylinder 4, and connect the other end to the MR8741 storage recorder 2. refer to Figure 3 The sealed small steel cylinder 4 can be placed in the iron drum 3. The wires of the K-type thermocouple 5 are connected through the exhaust port on the top of the constant temperature drying oven 1.
[0058] Step 5: Bury the small steel cylinder 4 with the K-type thermocouple 5 attached into the iron drum 3, close the door of the constant temperature drying oven 1, and let the constant temperature drying oven 1 continue to maintain the set temperature. Turn on the MR8741 storage recorder 2 and record the data.
[0059] After heating for a period of time, the time when the exothermic peak appeared in the two groups of explosive samples was determined by plot analysis. By comparing the time sequence of the exothermic peak, the heat resistance of ammonium nitrate explosive and emulsion explosive was evaluated.
[0060] The decomposition of explosives is a continuous process. When a sample of explosives undergoes violent decomposition, a dramatic exothermic peak appears on the temperature-time curve. The heat generated during decomposition is converted into an electrical signal by a K-type thermocouple 5 attached to the outer wall of the small steel cylinder 4 and transmitted to the MR8741 storage recorder 2. The control device then plots and analyzes the data, resulting in a significant exothermic peak on the temperature-time curve. By comparing the temporal order of the exothermic peaks, the heat resistance of the explosive can be evaluated.
[0061] refer to Figure 4 Pure ammonium frying explosives only showed a significant exothermic peak after 166 minutes at 240℃; while ammonium frying explosives with added heat-resistant inhibitors only showed a significant exothermic peak after 252 minutes, indicating that the heat resistance of ammonium frying explosives with added heat-resistant inhibitors is better than that of pure ammonium frying explosives.

[0064] Optionally, the temperature-time curve can be further displayed to the user.
[0065] Specifically, the user inputs the expected environmental parameters and / or the isothermal duration for the target cavity. If there is only one cavity, the default input is the expected environmental parameters and / or isothermal duration for that cavity. If the user does not input the isothermal duration, the preset duration will be used, which can be set to 200 minutes, 300 minutes, 350 minutes, etc.
