Description
Technical field
The invention belongs to field of coal mine safety, relate to a kind of protrusion-dispelling dynamic management and analytical approach and system.
Background technology
Coal and gas prominent (hereinafter referred to as " giving prominence to ") is a kind of extremely complicated dynamic phenomenon, and destructive power is strong, harmfulness is large, and a large amount of gas gushed out instantaneously may cause the secondary enlargement disaster accidents such as secondary gas explosion, gas asphyxiation.Outstanding accident causes huge economic loss and bad social influence to mine, becomes one of the principal element of restriction mine safety, High-efficient Production.China gives prominence to one of the most serious country of disaster in the world, projecting mine is many, distributional region is wide, outstanding accident is many, the number of casualties is many and along with the increase of the pit mining degree of depth and intensity, coal and gas prominent danger strengthens day by day, and the difficulty of outburst prevention work also increases gradually.So, relevant institutions standard and the management expectancy of the outstanding aspect of control are strict gradually, " control coal and gas prominent detailed rules and regulations " also upgrade to " control coal and gas prominent regulation ", define the outburst hazard prediction of a set of collection region, the inspection of region outburst prevention measures, region measure effect, area validation, and the prediction of workplace outburst hazard, the inspection of workplace outburst prevention measures, workplace measure effect, safety prevention measure in interior region and local " quaternity " comprehensive outburst control measure technical system, effectively control the generation of coal and gas prominent accident.
But due to various consciousness, management and technical elements reason, China still adopts Traditional Man pattern to protrusion-dispelling management, analysis, in daily protrusion-dispelling management with in implementation dynamics, there is protrusion-dispelling and manage not science, protrusion-dispelling execution many situations lack of standardization, in protrusion-dispelling information analysis, there is only heavy surface data result, do not carry out unilateral, the coarse analysis situation of concentrating statistics, detail analysis comprehensively, cause outstanding accident still often to occur so far.As can be seen here, improve Safety of Coal Mine Production level, the generation of containment colliery severe and great casualty, not simple is the problem of outburst prevention measures, protrusion-dispelling management and the not science analyzed, lack of standardization, not meticulously also occupies very large responsibility.Protrusion-dispelling managerial personnel carry out work with subjective consciousness and experience, the planning and implementation of the information work of Safety of Coal Mine Production lacks the tissue of competent authorities, coordination and support, and this traditional management mode and means can not adapt to Gas Disaster accident now complicated and changeable again.
In recent years, along with calculating and the infiltration of informationization technology, the concept of " digital mine " is also frequently mentioned, but really to implement in safety in production and what have effect is not too many, mostly rest on the data management to observation data, and scale is less.For mine control coal and gas prominent, how according to protrusion-dispelling technology and management expectancy, for current protrusion-dispelling technology and management aspect deficiency, determine the management of scientific and rational protrusion-dispelling and analytical technique, advanced computer technology is utilized to develop the protrusion-dispelling supervisory computer infosystem being applicable to Safety of Coal Mine Production, promote protrusion-dispelling management and science, the specification analyzed, become more meticulous level, becomes the task of top priority.
