Abstract
The invention relates to a real-time monitoring system for a coal mining heading face. The real-time monitoring system comprises a sensor system, a wireless data collector, a mining explosion-proof power source, an underground monitoring substation and an aboveground server monitoring system. The sensor system includes a stress sensor and a methane sensor, and the wireless data collector is connected with the stress sensor and transfers data collected by the stress sensor to a wireless receiver in the underground monitoring substation. The underground monitoring substation is provided with embedded system collection software, and stores, analyzes and processes monitoring signals, and if data abnormality occurs, an alarm is sent by an underground sound and light alarm. Data that have been processed are also transmitted to the aboveground monitoring system through an optical fiber ring network. The aboveground server monitoring system includes a sound and light alarm which gives out an alarm in time when abnormality occurs in terms of monitoring signals. The system can realize real-time monitoring and early warning for the heading face.
Description
Technical field
The present invention relates to a kind of driving face monitoring system, be specifically related to a kind of real-time monitoring and early warning system that is used for driving face.
Background technology
The China's coal-mine accident takes place frequently, and brings threat for miner's the personal safety and the safety in production in colliery.In recent years, along with country, the mine is to the attention of safety and the lifting of colliery profit norm, the input of safety of coal mines aspect continues to strengthen.Monitoring technology then is a focus of studying both at home and abroad in recent years, and this technology is provided with the monitoring point in the scope of mine, then transfer of data is arrived storage, treating apparatus, and then with analysis software the contingent disaster in mine is analyzed.
The coal mine roadway driving is abominable, the dangerous big work of a kind of condition of work.At present, the driving in mine mainly relies on experience, and particularly the driving under geological conditionss such as heavily stressed, high gas lacks effective monitoring means, especially can monitor in real time and the equipment and the method for early warning.
The driving in colliery; Needs one are enclosed within the stress monitoring system of down-hole ability real-time monitored and early warning minority measuring point, the stress state of each measuring point of underground work personnel ability real time inspection, and can carry out real-time early warning according to settings; For downhole safety production provides safeguard; Simultaneously abovegroundly can see monitored data in real time synchronously, it is capable that control well is divided into received shipment, and the stress state and the gas density information of development end is provided for the mine administrative staff.
In conjunction with above demand; Exploitation one cover driving face stress and gas monitoring system; A complete set of system is installed near the work plane operating personnel, shows the stress monitoring data in real time, according to field condition threshold value of warning is set; Reach threshold value and carry out display alarm and drive sound and light alarm, in time report each measuring point stress state for the Field Force.
Summary of the invention
Technical scheme of the present invention is: a kind of driving face monitoring system comprises sensing system, data acquisition device, mine explosion-suppression power supply, underground monitoring substation, aboveground monitoring system; Sensing system comprises strain gauge and firedamp sensor; Firedamp sensor and strain gauge are arranged in the getting working face range of disturbance; The data acquisition device is connected with strain gauge, the wireless receiver of transfer of data to the underground monitoring substation that strain gauge is gathered; The mine explosion-suppression power supply is connected with the underground monitoring substation; The underground monitoring substation is provided with the embedded system acquisition software, monitor signal is stored, analyzes and handles, if data occur then having the down-hole audible-visual annunciator to send warning unusually; Data after the processing also transfer to aboveground monitoring system through optical fiber ring network, and aboveground monitoring system comprises audible-visual annunciator, occur reporting to the police timely when unusual at monitor signal.
The installation of driving face monitoring system comprises: the installation of the installation of the installation of strain gauge, the installation of firedamp sensor, underground monitoring substation, the installation of mine explosion-suppression power supply and down-hole, aboveground audible-visual annunciator.
Description of drawings
Fig. 1 is a system layout of the present invention;
Fig. 2 is construction embodiment of the present invention;
The specific embodiment
Strain gauge is along the monolateral layout of digging laneway: 9 stress measuring points, and totally 11 passages, every group of two strain gauges connect preceding two passages of wireless collection device, need 5 of wireless collection devices altogether.Every group of measuring point spacing 15m, the vertical rib of measuring point arranges that fitting depth is respectively 7m, 14m, spacing 1m; Leading measuring point is to boring head deflection 45 degree (see figure 2)s, and fitting depth is 14m.Along with the propelling of work plane, strain gauge moves group, realizes circulatory monitoring.The wireless collection device is being suspended on the anchor pole near the strain gauge nearby.
Drilling construction requires and parameter:
(1) bore diameter: φ 42-45mm, use the construction of φ 42mm drill bit.
(2) drilling depth: 7m, 14m; It is consistent with the fitting depth of strain gauge to hole.
(3) drillhole height: apart from tunnel seat earth 0.5～1.5m;
(4) bore direction: parallel coal seam aspect, avoid boring to get in the rock stratum;
(5) drilling hole stress sensor tubing length 9m, 15m.
(6) use mounting rod Installation Stress sensor;
(7) use oil pump to suppress, be stabilized in 5Mpa up to oil pressure to strain gauge.
Two firedamp sensors connect an acquisition module separately, and this acquisition module is installed in the Monitor Sub-Station of Less and by substation and supplies power to firedamp sensor.Firedamp sensor is furnished with convenient on-the-spot installation of junction box.Firedamp sensor is installed in respectively apart from driving face 15m and 40m, is suspended on the anchor pole nearby.Along with the propelling of work plane, firedamp sensor about 200 meters of the line of can considering to lengthen in advance, about 100 meters of every like this propellings are moved with substation.
The underground monitoring substation is placed on apart from work plane 80m-100m place, can directly be placed on base plate.Along with the propelling of work plane, about 100 meters move left and right once.For realizing the ground monitoring function, need from laying optical cable between near Monitor Sub-Station of Less to the optical cable interface.Reserve fiber lengths according to manufacturing schedule, reduce optical fiber and connect number of times.
The mine explosion-suppression power supply need connect to combine protects power supply AC127V or 660V.Be installed together with Monitor Sub-Station of Less, can directly be placed on base plate.Move with Monitor Sub-Station of Less.Cable can connect according to the on-the-spot guarantor's position of source of combining of exploitation nearby, has reserved respective length.
The down-hole audible-visual annunciator is installed in the Monitor Sub-Station of Less next door, is suspended on nearby on the anchor pole, moves with Monitor Sub-Station of Less.Aboveground audible-visual annunciator is installed in the monitor server next door.
