KMJ30 mining stress monitoring system software is installed on the host, the host is connected with the ground surface transmission interface through a cable, the ground transmission interface is connected with the mine pressure communication substation through a cable, and the mine pressure communication substation is connected with the fully mechanized support pressure recorders through cables. The coal face advance rate monitoring device is used for monitoring curve of pressure variation of a working face support, controlling falling, moving and lifting of the working face support, and monitoring advancing situation of the working face support at different positions by the aid of the fully mechanized support pressure recorders arranged at different positions.
Description
Technical field
The utility model relates to a kind of coal-face propelling degree monitoring device, by arranging the fully mechanized mining supporter manograph at the coal-face hydraulic support, determine the process of shifting of falling of support by the variation of poppet pressure, thus the purpose of the monitoring face of realization propelling degree.
Background technology
The propelling degree refers to work plane in process of production, the advance of the face distance of every day.It has directly reflected the speed of face propulsion speed.
Show that after deliberation what of coal production advance of the face degree not only reflected, and be associated with a plurality of factors in the recovery process.At first advance of the face degree is to the coming the pressure cycle and come the pressure degree that material impact is arranged of work plane, and the size of degree of propelling also directly influences the gas emission of work plane in addition.When the easy spontaneous combustion of exploitation coal seam, the size of propelling degree has extremely important meaning for the safe working in colliery.Therefore, can better instruct coal production to the monitoring of advance of the face degree, exploitation ensures safety.
And present monitoring method at advance of the face degree, adopt the method for manual record mostly, this method is not only loaded down with trivial details but also have retardance, after normally each back production class comes off duty, by the operator on duty control room of reporting for work, and also can't illustrate for the propelling degree of work plane diverse location.Therefore, adopt advance of the face degree monitoring system, can realize the work plane diverse location is advanced the real-time monitoring of situation, more help instructing and produce.
The utility model content
The purpose of this utility model provides a kind of coal-face propelling degree monitoring device, and this device has reduced labour intensity, has improved operating efficiency.
To achieve these goals, the utility model is by the following technical solutions:
A kind of coal-face propelling degree monitoring device, it comprises: communication substation and at least one fully mechanized mining supporter manograph are pressed in main frame, ground transmission interface, at least one ore deposit that KMJ30 mine monitoring stress system software is housed; This main frame is connected with this ground transmission interface by cable, and this ground transmission interface presses the communication substation to link to each other by transmission cable and this ore deposit, is connected by cable between this ore deposit pressure communication substation and this fully mechanized mining supporter manograph.
The pressure sensor of described fully mechanized mining supporter manograph adopts pressure resistance type or capacitance type sensor.
Described main frame also is connected with the UPS back-up source.
On the transmission cable between described ground transmission interface and the described ore deposit pressure communication substation arrester is installed.
The beneficial effects of the utility model: the resulting coal-face propelling of the utility model degree monitoring device, be used for monitoring face poppet pressure change curve, grasp falling frame, move frame, rising the frame process of force piece; By arranging the fully mechanized mining supporter manograph, can grasp the propelling situation of work plane diverse location at diverse location.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of coal-face propelling degree monitoring device, it comprises: communication substation 3 and at least one fully mechanized mining supporter manograph 4 are pressed in main frame 1, ground transmission interface 2, at least one ore deposit that KMJ30 mine monitoring stress system software is housed; This main frame 1 is connected with this ground transmission interface 2 by cable, and this ground transmission interface 2 presses communication substation 3 to link to each other by cable and this ore deposit, is connected by cable between this ore deposit pressure communication substation 3 and this fully mechanized mining supporter manograph 4.
Fully mechanized mining supporter manograph 4 is installed on the working surface hydraulic support, and its pressure sensor adopts pressure resistance type or capacitance type sensor.
Main frame 1 is connected with UPS back-up source 5.UPS back-up source 5 is a kind of uninterrupted power source, and being used for provides uninterrupted power supply for whole monitoring system.
On the transmission cable between described ground transmission interface 2 and the described ore deposit pressure communication substation 3 arrester can be installed.Prevent thunderbolt with the protection control signal.
Main frame presses the communication substation to patrol and examine to described each ore deposit, gathers the data of each substation; Main frame comprises data sink, and data storage device and KMJ30 mine monitoring stress system software by this software, can be presented at the poppet pressure change curve on the screen, moves past journey by determining that support falls, thereby obtains advance of the face degree situation.
Described ground transmission interface is to convert downhole system to terrestrial interface.
The ore deposit presses the communication substation to connect a plurality of fully mechanized mining supporter manographs by cable.The ore deposit is pressed the communication substation generally to be positioned over tunnel, work plane the place ahead two and is helped the place, and its effect is to be used for record and storage fully mechanized mining supporter manograph data monitored.
Described ore deposit presses the communication substation to be responsible for the monitored area of down-hole, and each ore deposit presses the communication substation can connect a plurality of fully mechanized mining supporter manographs.
Described poppet pressure recorder is installed on the working surface hydraulic support, what be used for monitoring and store support falls, moves, rises process, and its record data are reached main frame, by KMJ30 mine monitoring stress system software analysis poppet pressure, obtain support and fall frame, move frame and rise the overall process of frame, thereby obtain the propelling degree of work plane.
The installation site of fully mechanized mining supporter manograph can be installed one by per ten according to face condition, or presses work plane upper, middle and lower diverse location and arrange.During installation, post before and after the support is respectively drawn a hydraulic oil pipe, be connected on the tubing interface place of fully mechanized mining supporter manograph, with cable the fully mechanized mining supporter recorder is coupled together with ore deposit pressure communication substation then and get final product.
More than be preferred embodiment of the present utility model and design graphic; above-mentioned preferred embodiment and designing graphicly only illustrates; be not to be used to limit interest field of the present utility model; all with equalization technological means or be the interest field that contained of the application's claim and the implementer does not all break away from protection domain of the present utility model.
