In the many open coal mines of China, because the little coal mining of history forms a large amount of empty lane and goaf, outcrop of coal seam are more shallow in addition, cause defining large area flame range.The major measure taked at present for flame range blast working first cools to less than 50 DEG C to the water filling of big gun hole, then carries out charge explosion according to " 9 people, 3 minutes, 8 holes ".But only rely on water filling most of big gun hole that lowers the temperature often to be difficult to be reduced to below set point of temperature, seriously restrict construction speed, and the bounce-back of part big gun hole temperature is rapidly, causes certain potential safety hazard.
For this present situation, some enterprises being active in this field propose some improved plans through long felt, by using novel temperature insulating material or safeguard procedures to protect explosive, reach the object of essential safety.Such as Guangdong Hongda Blasting Co., Ltd. discloses a kind of temperature-resistance thermal-insulation jacket structure for charge explosion in high temperature big gun hole in the patent No. 201410206203.6; Gezhouba Pu Yili Co., Ltd discloses a kind of blast hole loading structure being applicable to flame range explosion at patent No. CN201420034267.8, and discloses the resistance to heat-proof device of a kind of flame range blasting charge in the patent No. 201420293241.5.If these heat isolating structures or device do not carry out a large amount of experiment tests to prove will certainly bringing without predictable potential safety hazard before being generalized to Application in mining.But also do not have one can simulate flame range demolition site in test base, for detecting the device of these safeguard procedures feasibilities at present.
Utility model content
For existing problem, the purpose of this utility model is to provide a kind of pick-up unit detecting the simulation flame range blasting protection structure of Explosive protection measure feasibility.
To achieve these goals, the technical solution of the utility model is: a kind of pick-up unit of simulating flame range blasting protection structure, comprise foundation ditch (1), it is characterized in that: in foundation ditch (1), be filled with sand particles (2), heating reinforcing bar (5) is furnished with in described foundation ditch (1), be connected by heater strip (6) between heating reinforcing bar (5), described heating reinforcing bar (5) is connected with power supply by temperature detect switch (TDS) (7), temperature sensor (8) is provided with in described foundation ditch (1), the middle part that test tube cartridge bag (3) is placed in foundation ditch (1) contacts with sand particles (2), choke material (4) is filled in the top of test tube cartridge bag (3), the primacord fuse (9) of test tube cartridge bag (3) reaches foundation ditch (1) top and is connected with primer detonator (10), described primer detonator (10) is connected with initiator (11), the top that the explosion velocity p-wire (12) be connected with test tube cartridge bag (3) reaches foundation ditch (1) is connected with explosion velocity tester (13), the temperature test wire inserted in test tube cartridge bag (3) is connected with temperature measuring device (14), video camera (15) is installed near described foundation ditch (1).
Adopt technique scheme, in foundation ditch, transfer heat to sand particles by power supply heating heating reinforcing bar and heating wire, thus the high temperature blasting operation environment of simulation flame range demolition site.Temperature signal is passed to computing machine by temperature sensor, computing machine controls temp control switch and automatically closes according to the temperature value arranged, under making test tube cartridge bag be in isoperibol, thus whether validation test tube cartridge bag is safe and reliable at the temperature, time conditions of regulation.As auxiliary monitoring, this proving installation serviceability temperature tester monitoring and test tube cartridge bag temperature variations in time, uses the whole experimentation of video camera remote monitoring.If be still in safe temperature range when reaching the temperature that cartridge bag after official hour requirement is not blasted yet or temperature measuring device shows in cartridge bag, so can illustrate that this kind of thermal insulation safeguard procedures are safe and reliable.This cartridge bag carried out detonating can measure to fixed temperature, the explosion velocity situation of change of explosive and primacord fuse under the time finally by connecting initiator, thus again verify that whether safeguard procedures are reliable.This structure achieves the basic demand of the explosion test under the various condition of simulation flame range.Tester can carry out Real-Time Monitoring to whole test process in safety zone, ensure that the safe and reliable of test process.The material of all test macros and the equal wide material sources of servicing unit, construction technology is simple, has good practicality.
In such scheme: the outside parcel insulation material layer of described primacord fuse (9) and explosion velocity p-wire (12).Primacord fuse and explosion velocity p-wire can be avoided like this to be subject to the impact of high temperature.
In such scheme: described insulation material layer comprises the ceramic fiber or adiabatic carpet veneer that are wrapped in inside, is also bonded with masking foil or aluminium foil ply of paper outward at ceramic fiber or adiabatic carpet veneer.
Beneficial effect: the utility model, in foundation ditch, has transferred heat to sand particles by power supply heating heating reinforcing bar and heating wire, thus the high temperature blasting operation environment of simulation flame range demolition site.Whether validation test tube cartridge bag is safe and reliable at the temperature, time conditions of regulation.As auxiliary monitoring, this proving installation serviceability temperature tester monitoring and test tube cartridge bag temperature variations in time, if be still in safe temperature range when reaching the temperature that cartridge bag after official hour requirement is not blasted yet or temperature measuring device shows in cartridge bag, so can illustrate that this kind of thermal insulation safeguard procedures are safe and reliable.This cartridge bag carried out detonating can measure to fixed temperature, the explosion velocity situation of change of explosive and primacord fuse under the time finally by connecting initiator, thus again verify that whether safeguard procedures are reliable.This structure achieves the basic demand of the explosion test under the various condition of simulation flame range.Tester can carry out Real-Time Monitoring to whole test process in safety zone, ensure that the safe and reliable of test process.The material of all test macros and the equal wide material sources of servicing unit, construction technology is simple, has good practicality.This pick-up unit can also promote the explosive test for carrying out other environment and the explosion of condition Imitating flame range.
