Description
Technical field
The present invention relates to mine safety field, be specifically demolition site monitoring, roof pressure monitoring, Tailings Dam monitoring, mine drainage ventilation monitoring monitoring and subsurface environment amount monitoring composition mine safety monitoring total management system.
Background technology
Rich coal resources in China, but mining conditions is complicated, and natural calamity is serious, and the mine of 47% belongs to high methane or Gas Outburst mine.Under the promotion that current coal market is in great demand, there is assault and produce or blindness overyielding in Part Coal Mine, causes mine safety accident rate in recent years to remain high.For ensureing the safety in production in colliery, except strengthening coal mine safety management consciousness further, key sets up the mining Safety monitoring total management system of underground coal mine, formed in coal mine, the reliable safe early warning mechanism in down-hole and administrative decision information channel.So the production of present modern mine not only to solve exist in coal production process safety problem, the production automation problem, understand the various information relevant to production and operation again.Set up safety in production, scheduling and network system for managing, overall understanding is produced to aboveground, downhole safety, produce by information commander promptly and accurately and prevent the generation of various accident, having become the problem that Coal Mine Design work must solve.
Although nearly country in recent years more and more payes attention to mine safety, the process used from reality we think mainly there is following problem:
1. mine safety monitoring total management system function singleness;
2 sensor mass and poor performance;
The key technology that the methane transducer connected with mine safety monitoring total management system, CO sensor sensor have become Comprehensive Control of Mine Gas and monitored coal spontaneous combustion hazard prediction is equipped, and is more and more subject to the most attention of applying unit and researcher.But in using at the scene, although system host, substation and software are constantly upgraded, but the sensor of domestic safety detection almost all adopts carrier catalyst element, there is short, poor work stability and the adjustment phase is frequent, sensitivity drift and the shortcoming such as manufacture craft level is low in application life in China's carrier catalyst element for a long time always, seriously govern the normal detection of mine pernicious gas.Have strict regulation to the adjustment of methane transducer in " safety regulations in coal mine " in addition, adjustment need of work special implement and Standard Gases sample, have certain requirement to the technical level of adjustment personnel.A lot of colliery often can not be safeguarded and adjustment system, even never adjustment owing to lacking the reasons such as professional and technical personnel on time, seriously constrains the normal detection of mine pernicious gas.
3. communication protocol is lack of standardization, and integration is poor;
Because neither one meets the bus standard of the particular/special requirements such as mine electrical explosion proof, so the communication protocol of the monitoring and controlling system of existing manufacturer nearly all adopts special separately, incompatible.Lack interoperability, interchangeability between different manufacturers product, therefore integration is poor, is not easy to expanding of system function.In use, though peer machine is through repeatedly upgrading, still can not realizes effectively sharing of system resource, define one by one independently " information island ", seriously hinder the further raising of mine safety production managerial skills.
4. diagnostic function has to be strengthened, and the maintainability of system is low;
Site plant on-line fault diagnosis, warning, writing function are not strong, the remote parameter setting difficulty of site plant, the maintainability of influential system.As the supplementary means of management maintenance monitoring system, part system can only be diagnosed the communication condition of system, can not the character of failure judgement and trouble point in detail.But requirement can be judged rapidly between substation, sensor or cable fault in real work, or short-circuit alarming and the difference between truly transfiniting, for attendant provides type and the orientation of fault, so that handling failure place rapidly.
5. field control and maintenance levels shortcoming;
Although monitoring mining monitoring system must be equipped by each province and city department in charge of the coal industry of China all high methane in each large, medium and small colliery of Compulsory Feature or Gas Outburst mine, and the management intensity again increased in recent years mine safety production, but some local state-owned coal mines, particularly small towns small coal mines, most owing to lacking professional and technical personnel and can not the normal furnished system of operation and maintenance, even adjustment is not carried out to the sensor that system connects.In addition, most state-owned coal mines also also exist management system in monitoring not well established, to the monitoring managing system existed perform tight, to problems such as the supervision and management of monitoring and controlling system are not in place, seriously govern the normal operation of mine safety monitoring total management system.
