Technical field
The utility model relates to the top board dynamic monitoring system of colliery underworkings and work plane.
Background technology
In all kinds of coal mining accidents, the roof accident position of still ranking forefront.Shift along with the increase of the raising of production capacity, mining rate with to deep mining, the roof safety problem more and more shows especially, is mainly reflected in three aspects: the one, and be the stability of the roadway of principal mode with the bolt support.Does existing supporting parameter have much safety factor on earth? need monitoring means to assess and potential danger forecasting.The 2nd, is leading bearing pressure influence basin much? how high is the pressure intensity? is the high peak position of bearing pressure wherein? how many be bearing pressure speed of advancement? Deng, with other monitoring problems such as advance support and the closely related factors of bump; The 3rd, coal face support stability and safety.How is the scaffold working face duty? whether does supporting satisfy the requirement of control top board? be stope overlying rock first weighting and periodic weighting step pitch much? when pressing present support system there are much influences etc.At present, existing monitoring means all is independently on the colliery, comprises fully-mechanized mining working surface hydraulic support monitoring system under the coal mine, back and surrounding rock separation layer monitoring system, the leading bearing stress monitoring system of coal petrography, roadway surrounding rock bolt support stress monitoring system etc.Because each monitoring means is separate, so can not carry out comprehensive analysis processing to the data that monitor; Except monitoring means was independent, the independent monitoring of each mine main had also restricted the resource-sharing in whole mining area.Therefore, make full use of Internet resources, set up a cover " based on the mine roof safety monitoring system of ethernet technology ", safety of coal mines is on a new level to have a practical significance to impelling, and has important application value in national colliery.
The utility model content
The purpose of this utility model proposes a kind of full mine ore deposit of setting up based on the Ethernet platform of realizing and is pressed in the comprehensive monitor system of line monitoring exactly for satisfying the coal mine downhole safety needs.The computer network platform that this system utilizes mining area or mine to set up is formed mineral bureau's level mining area monitoring network with each mine main top board dynamic monitoring system, realizes the automation and the information sharing of ore deposit pressure monitoring.
The technical solution of the utility model is: it comprises four subsystems in down-hole, it is down-hole fully-mechanized mining working surface hydraulic support monitoring system, back and surrounding rock separation layer monitoring system, the leading bearing stress monitoring system of coal petrography, roadway surrounding rock bolt support stress monitoring system, the mining monitoring main website that the data that it is characterized in that above-mentioned four subsystems are sent to by the mine data communication cable that the down-hole is provided with, mining monitoring main website is sent to the mine data communication interface of aboveground setting by compatible telephone line or ethernet ring network switch, by the mine data communication interface to monitor server, monitor server is sent to the network switch again, to the mining area LAN, and be sent to the GPRS transceiver by the network switch to the GPRS public data network.Monitor server of the present utility model adopts Industrial Personal Computer (IPC), and the system monitoring analysis software adopts SQL Server database, and the CS/BS structure is carried out multinomial integratedly, and concurrent mechanism supports the diversification parameter to analyze and warning function.
The treatment step of monitoring analysis software is: 1, according to the mine situation stope top board parameter and alarm threshold value are set earlier; 2, the real time data and the alarm threshold value that receive of monitor server compares, and comparative result exceeds threshold range, and software sends affair alarm information; 3, regularly deposit real time data in database simultaneously; 4, the data in the database are carried out trend analysis, multi-parameter association analysis and mining conditions comparative analysis; 5, above analysis situation is done following the processing according to the stope top board parameter of input again, the one, generate group financial statements, the 2nd, the integrated forecasting situation of the danger of output coal mine roof plate, the 3rd, output to the GPRS transceiver, authorized user is carried out the output of GPRS data.
Native system is layouted in the down-hole according to the occurrence characteristics and the physico-mechanical properties of coal rock layer, installs the sensor of four subsystems.Reflect the mathematics mechanical mode of adjoining rock stability state or prop duty according to dissimilar monitored data,, analyze and explain, reach following automatic identification decision: 1) roadway surrounding rock safety by Industrial Personal Computer (IPC) to the monitored data of four subsystems; 2) or the stability of end support and reliability; 3) or the duty of anchor pole and support; 4) or leading abutment pressure distributes and transfer characteristic etc.Four subsystems are adjacent in twos, cover the gamut of inside and outside stress field, and at one time, information is pressed in the ore deposit that can monitor the diverse location place; Along with roof strata moves to remarkable motion metastable, again in the overall process of roof weighting, the abutment pressure peak will experience earlier expansion forwards, the reciprocal process that shrink to the work plane direction back, above-mentioned four subsystems will experience pressure in succession and manifest peak phase, and people just can predict the information state of adjacent system (next subsystem) from the information state of last sub-system (a last subsystem) like this; In like manner, can be from the checking of the current information state of next subsystem before this in the correctness of a last sub-system prediction, thus improve the science and the accuracy of top board dynamic monitoring.
Native system has been realized following advantage: the utility model has been realized the data sharing in full mining area.Its theoretical foundation is based on " the inside and outside stress field theory " that mine pressure distributes.Advance with stope, the distribution of overlying rock motion and mine pressure all is among the continuous variation, and wherein overlying rock (comprising top board) laws of motion have determined the regularity that mine pressure distributes and manifests.Disclosing that overlying rock motion, mine pressure distribute and the causal basis of strata behaviors on, the strata behaviors information that can obtain by actual measurement just, the situation of change of motion of prediction overlying rock and mine pressure distribution.
Coal mine roof plate dynamic monitoring key is the monitoring that stope mine pressing is manifested the roof strata motion that has a significant effect, and the roof strata motion has periodically, and monitoring roof strata cycle movement process is the core of monitoring.In roof strata cycle movement process, mine pressure distributes and to demonstrate fully with the regularity that manifests: same position is in the different time ore deposit and presses that to manifest rule different; In the different time, the ore deposit at diverse location place is pressed and is manifested the rule difference.The utility model has realized in the overall process of top board cycle movement that as far as possible in the larger context the multiple ore deposit of the omnidistance monitoring information of pressing is also carried out analysis-by-synthesis, thereby obtains prediction result accurately.
Characteristics of the present utility model also are: four sub-system layout schemes according to above-mentioned top board dynamic monitoring theory carry out.Monitoring system adopts two-stage bus tree, and the underground monitoring network is the center with the stope, and layout draws near.The order that draws near is successively:
