Description
Technical field
The present invention relates to the dangerous automatic analysis system of bump and the method for drilling cuttings method, be used for the colliery dynamic disaster and detect and early warning.
Background technology
In the dangerous monitoring and warning of bump field, present on-the-spot forecast both domestic and external is mainly take the drilling cuttings method as main.Drilling cuttings method (coal dust boring method) is that (a kind of practical reliable method of shock hazard is differentiated in 40～50mm) borings according to the coal dust amount of its discharge and Changing Pattern and macroscopical dynamic phenomenon by bore a minor diameter in the coal seam.
Bump seminar of Fushun Mine Administration, bump seminar of Fuxin Mining Technology College and bump seminar of Longfeng Mine, Fushun Mineral Administration have delivered " research research and the application of drilling cuttings method " paper in 1985 at " Fuxin Mining Technology College's journal ", the laboratory test of utilizing homemade confining pressure device to carry out, and the calculated results, experimental study goes out a whole set of ways and means of determining the danger of burst index and judging the danger of burst degree of drilling cuttings method, specifically provided Longfeng Coal Mine exploitation bump dangerous coal seam examination criteria and impacted index, and used in the dragon and phoenix colliery.
Zhaoyang rises professor and equals to deliver " exploration of drilling cuttings method monitoring pressure from surrounding rock " paper at " geotechnical engineering journal " in 1987, has proved coal powder quantity of bore and has changed with surrouding rock stress and have certain relation.Deliver " the critical drillings quantity research of bump " paper in 1989, studied the Changing Pattern of drillings amount under the different geological conditions.
At present, both at home and abroad when application drilling cuttings method is carried out the shock hazard check, it mainly is the method realization by " piece of cloth, a steelyard, one-pen, a piece of paper ", the workman that namely drills is layered on a piece of cloth on the ground under the outlet of drilling rod row powder, whenever creep into one meter, the workman just is recorded in the number of times of the macroscopic appearances such as the crown drill that occurs in this meter drilling process, bit freezing, suction brill and coal big gun in the statistical form, and each meter rod boring finishes, just the drillings on the cloth is used to claim weighing, weighing result is recorded in the statistical form.Continue to creep into, the workman repeats top method and carries out data statistics.The method carry out shock hazard pass judgment on its shortcoming be operating personnel in the implementation process dangerous large, workload large, the operate miss that varies with each individual, thereby cause the inaccuracy of evaluation result, unreliability and not scientific.
At present, also there is not the drilling cuttings method to judge bump intelligent device or system both at home and abroad.Low in order to solve based on the shock hazard judge intelligent level of drilling cuttings method, testing process is greatly dangerous and workload is large, overcomes the operate miss that varies with each individual, the invention colliery dangerous automatic analysis system of drilling cuttings method detection bump.
Summary of the invention
The purpose of this invention is to provide a kind of shock hazard intelligent appraisement system based on the drilling cuttings method, this system can be widely used in the dangerous check of bump of drilling cuttings method, based on the drilling cuttings method, realizes the standard of shock hazard check, reliable, safety, succinct.
A kind of shock hazard intelligent appraisement system based on the drilling cuttings method, this system comprises following three parts: first: the automatic weighting case; Second portion: handheld operation device; Third part: data processing software.Realize the intellectuality judgement of shock hazard by above three part collaborative works.
Intelligent weight box is comprised of material-gathering device, weight sensor, digital display table, automatic discharge unit and data wireless transceiver module five parts.Weight box has realized that by above five parts electronic coal dust is weighed and the intelligent data transmitting-receiving.Weight sensor and material-gathering device contact to record the weight that falls into drilling cuttings in the Material collecting box for harvesting by effective.Linked to each other by shielding line between sensor and the digital instrument.Linear electric motors control automatic discharge unit, linear electric motors receive the discharging hatch door start signal that sends over from the handheld operation device, hatch door autoshutdown when discharging is complete.Link to each other by 485 communication interfaces between radio receiving transmitting module and the digital display table, can be by this interface control instrument zero clearing and the associative operation such as reset.
Material-gathering device adopts the funneling design of class in order to the collection coal dust that auger stem is discharged in the process of drilling, and Material collecting box for harvesting has the automatic discharging function.
The Material collecting box for harvesting bottom is 37 ° of inclination angles, have simultaneously the discharging hatch, make the coal dust that gathers by being with angled ramped bottom surface all to focus on the discharging hatch, there is a baffle plate that links to each other with transmission gear for electric motor the discharging opening lower end, thereby can realize the automatic discharging function by forward and reverse rotation of motor.
Weight sensor is responsible for gathering the weight data of coal dust in the Material collecting box for harvesting, adopts Design of Cantilever Beam, with the accuracy that realizes weighing under the dynamic condition.
