Thinking about intelligent technology of rockburst prevention and controlled mining in rockburst mine

In view of the technical problems faced by the intelligent working face of deep rockburst mine,focusing on the goal of safe,efficient and intelligent mining of rockburst coal seam,the new generation of information technology is applied to mine production activities and rockburst prevention management,and the technical idea of intelligent rockburst prevention and control mining is put forward for the first time. Its scientific connotation and technical approaches are as follows:first,through the data transmission platform,quickly collect the regional coal rockburst risk information and real-time information such as equipment,working condition environment and personnel positioning of the whole working face,and establish a multi-source information database of rockburst and intelligent mining;Secondly,the distributed data acquisition system with high throughput and low delay is adopted to realize the cleaning,storage,clustering and fusion of multi-source heterogeneous data,dynamically couple the risk information of rockburst monitoring and early warning with intelligent mining,and build an intelligent big data platform for rockburst prevention;Finally,on the basis of accurate identification and data fusion of multi-source rockburst information,an intelligent mining response control system with interconnection,analysis and decision-making,dynamic prediction and collaborative control is developed. On this basis,an intelligent rockburst prevention and mining control model with the su perposition of shearer self adjustment,support self adaptation,rockburst prevention risk self sensing and self early warning is established,match the mining intensity with the impact risk,and finally form a new intelligent impact prevention and control mining mode of non intervention,self decision-making,self-control and self optimization. This technology organically combines the impact risk prediction,prevention and control with the intelligent mining system to form an intelligent response closed loop,which can ensure the efficient feedback of rockburst early warning information and realize the intelligent operation of mining,transportation,safety guarantee and other processes.
