Abstract
Method of monitoring coal mining solid pack pressure, suitable for monitoring pressure situation of goaf pack in mining wells solid packing and coal mining process. Disposing a plurality of packs pressure monitors in packing comprehensive goaf in rows, each row of pack pressure monitors are all disposed uniformly along the working surface; when collecting data, connecting communication line of each row pack pressure monitors with main communicatin line in coal transport lane through junction box, that is the communication line of pack pressure monitor is connected to the main communication through junction box, and then connected with main communication station through the main communication line, at last transmitting data of main communication station to ground data reception system through telephone lines to monitor pressure situation of solid pack on line, and using monitoring host to analyze the pressure data to prevent damage caused by the goaf pack. The invention is provided with simplr method, easy operation, high accuracy, improved packing effect, and the invention can avoid potential safety problems.
Description
Technical field
The present invention relates to a kind of pressure monitoring method, especially a kind of method of monitoring coal mining solid pack pressure that is applicable to well industrial and mineral mountain solid filling coal-mining technique.
Technical background
At present, the solid filling coal-mining technique reduces the distortion of overlying strata key stratum with it, reduces ground settlement, makes full use of the superiority of discarding waste materials such as spoil, more and more by domestic and international application, and has produced good economic benefit and social benefit.In the solid filling coal-mining technique, after obturation charges into the goaf, propelling along with work plane, for the compacting situation of goaf filling body how on earth, go back the neither one solution to this problem at present, if can in time grasp the pressure condition of goaf filling body, not only help analyzing the grasp filling effect, and be convenient to by changing methods such as obturation character (proportioning, water content) and compacting situation, can improve the technology of filling at any time, improve filling effect, avoid potential safety hazard.
Summary of the invention
Technical problem: it is simple to the purpose of this invention is to provide a kind of method, easy to operate, the method for monitoring coal mining solid pack pressure that can accurately monitor the pressure condition of obturation.
Technical scheme: method of monitoring coal mining solid pack pressure of the present invention:
A, in the goaf of following the pre-filling that coal-face advances, divide many rows to bury a plurality of obturation pressure monitors at interval underground;
B, each obturation pressure monitor line that will respectively come with the pressure monitor connection cause in the junction box of fortune coal road;
C, carry out solid filling by row;
D, the junction box of utilizing the communication main line will arrange lead-in wire are contacted to the downhole communication main website more, constitute the mining face under mine data collecting system;
E, the ground data gathering system of utilizing telephone wire that the transfer of data of downhole communication main website to the monitoring main frame of accepting the unit by the monitoring main frame and be attached thereto is constituted, by the ground data gathering system pressure condition of solid filling body is monitored in real time, and by the monitoring main frame pressure data is analyzed, determine the effect of solid filling.
It is 2～4 rows that described branch is arranged the obturation pressure monitor of burying underground at interval more, and distance between row and row is 25～35m, and first row is about 15m from the distance of cutting eye, and the obturation pressure monitor that every row buries underground is 3～6; Described obturation pressure monitor evenly distributes along work plane.
Beneficial effect: adopt to combine in filling and adopt the goaf and arrange a plurality of obturation pressure monitors, dividing arranges puts, and each is arranged the obturation pressure monitor and all evenly arranges along work plane; During data acquisition, every row's obturation pressure monitor connection is linked to each other with the communication main line of fortune in the coal road by junction box, be that obturation pressure monitor connection is connected on the communication main line by junction box, then through communication main line incoming communication main website, after telephone wire import the data of communication main website into ground data and accept in the system, pressure condition to the solid filling body is carried out on-line monitoring, and by the monitoring main frame pressure data is analyzed, and determines the effect of solid filling.This monitoring method not only can accurately be monitored obturation pressure, and the data sync transmission can be analyzed, and grasps the filling effect that solid filling is mined so that in time understand.Its method is simple, and is easy to operate, and the accuracy height can improve filling effect, avoids potential safety hazard, has practicality widely.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
1-fortune coal road among the figure, 2-obturation pressure monitor, 3-cuts eye, the 4-goaf, the 5-junction box, 6-communication main line, 7-communication main website, 8-pressure monitor connection, 9-monitoring main frame is accepted the unit, the 10-telephone wire, 11-monitors main frame.
The specific embodiment
Below in conjunction with accompanying drawing one embodiment of the present of invention are further described:
Method of monitoring coal mining solid pack pressure of the present invention: in the goaf 4 of the pre-filling of the filling mining advance of the face, arrange 3 row's obturation pressure monitors 2, whenever arrange and put 3, distance between row and row is 25m～35m, first row is about 15m from the distance of cutting eye 3, the average buried depth of filling mining work plane is 350m, and face length is 50m, and propelling length is 460m.According to on-the-spot actual needs; obturation pressure monitor 2 can be 2～4 rows; every row buries 3～6 underground at interval; with pressure monitor connection 8 each obturation pressure monitor 2 line among each row are caused in the junction box 5 of fortune coal road 1; be protection obturation pressure monitor connection 8; dig a groove at its burial place, and carry out pre-buriedly, the time can avoid the impact failure of obturation pressure monitor connection 8 when charges fall the back from top.Then solid filling is carried out in the goaf of having buried obturation pressure monitor 2 underground by row, obturation pressure monitor 2 evenly distributes along work plane.Every row's obturation pressure monitor connection 8 all links to each other with the communication main line 6 of fortune in the coal road 1 by junction box 5.When obturation pressure monitor 2 is arranged as 2 rows, then be connected on the communication main line 6 by 2 junction boxes 5, when obturation pressure monitor 2 is arranged as 3 rows, then be connected on the communication main line 6 by 3 junction boxes 5, when obturation pressure monitor 2 is arranged as 4 rows, then be connected on the communication main line 6 by 4 junction boxes 5, the data of all obturation pressure monitors 2 are collected to junction box 5 through pressure monitor connection 8, and reach communication main website 7 by communication main line 6, be sent to the ground data gathering system by telephone wire 10 again, ground data is accepted system and is adopted the KJ216-J type to accept unit 9 and association's work of nature monitoring main frame 11 formations, by software programming, analyze by 11 pairs of pressure datas of collecting of monitoring main frame, the staff can the ground data gathering system to goaf 4 in the pressure condition of solid filling body monitor in real time, determine the effect of solid filling, and obturation pressure monitor 2 shows the pressure data of obturation.
