Description
Technical field:
The present invention relates to a kind of goaf on-line measuring device, belong to mining equipment technical field.
Background technology:
Mine fire is one of colliery major casualty, and spontaneous combustion in goaf accounts for the most at high proportion.Mine fire once occurs, the most then
Impact safety in production, heavy then burn coal resources and material equipment, even cause gas, coal-dust explosion.Therefore, goaf is carried out
The prediction of spontaneous combustion early warning of interior coal and location are significant for reducing life and property loss, it is critical only that of prevention
Every harmful gas concentration in goaf is carried out periodic detection.The collection of goaf harmful gas is mainly adopted by current each mining area
With Tube Bundle Monitoring System, utilize the infrared technique analysis to mine gas composition, it is achieved CO, CO2, CH4, O2, N2 (value of calculation)
Deng on-line continuous monitorings in 24 hours of gas content, its changes of contents situation is predicted.Tube Bundle Monitoring System mostly is large-scale
Mine detection design, a complete set of equipment is complicated, and management technique requires higher, and equipment cost is costly.And system is to spontaneous combustion of coal seam
The various gas marker analysis precisions of hidden danger are relatively low, and the sensor element life-span is short, need to often change, it is impossible to tracing detection
Forecast etc..Beam tube easily damages appearance breakage gas leakage and makes measurement result inaccurate；Meanwhile, beam tube system construction difficulty is big, no
Just safeguard.
Summary of the invention:
It is an object of the invention to provide a kind of simple in construction, easy to maintenance, data record can be carried out and can network with mine, executing
The goaf on-line measuring device that work difficulty is little.
For achieving the above object, the technical solution used in the present invention is:
A kind of goaf on-line measuring device, surveys instrument box, communication network including admission line, negative pressure pump, outlet pipe, health check-up
Network, ground monitoring computer.Admission line, one end of outlet pipe be connected with goaf chamber, admission line, outlet pipe
The other end and health check-up are surveyed instrument box and are connected, and negative pressure pump is arranged in admission line, health check-up survey instrument box by communication network with
Ground monitoring computer is connected.Periodically the gas in the chamber of goaf is pumped into gas control instrument case by negative pressure pump to carry out
Detection, gas control instrument case carries out display and the remote transmission of data.
The invention has the beneficial effects as follows, simple in construction, difficulty of construction is little, easy to maintenance, and degree of accuracy is high, can carry out data note
Record and remote transmission.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention.
In figure: 1 admission line, 2 negative pressure pumps, 3 outlet pipes, 4 gas control instrument casees, 5 communication networks, 6 ground monitorings
Computer.
Detailed description of the invention:

Dead zone chamber is connected, and admission line (1), the other end of outlet pipe (3) are connected with gas control instrument case (4), negative pressure pump
(2) being arranged in admission line (1), gas control instrument case (4) passes through communication network (5) and ground monitoring computer (6) phase
Connect.Periodically goaf gas is pumped into gas control instrument case (4) by negative pressure pump (2) to detect, gas control instrument
Case (4) carries out display and the remote transmission of data.
Operation principle: on-line measuring device is arranged near the chamber of goaf, admission line (1), the one of outlet pipe (3)
End is connected with goaf chamber, and admission line (1), the other end of outlet pipe (3) are surveyed instrument box (4) with health check-up and be connected, negative
Press pump (2) is arranged in admission line (1), the gas in the chamber of goaf under the effect of negative pressure pump (2) through admission line (1)
Inflow gas instrumentation case (4), returns through outlet pipe (3) after the various instrument in gas control instrument case (4) detects again
Flow in the chamber of goaf.Data after detection can pass through charactron field observation.Gas control instrument case (4) is built-in simultaneously
The ground monitoring computer (6) that the data of detection are sent to control room by communication network (5) by remote communication module is remembered
Record and display, it is also possible to carry out data transmission with neighbouring automatic monitored control system.
