The measurement of coal mine roadway deflection mainly comprises the roadway's sides amount of shifting near and roof-to-floor convergence.The coal mine roadway roof-to-floor convergence can respectively be laid an observation stake by top board, base plate and be measured.But in real work, the amount of shifting near of roof and floor is difficult to carry out long-term observation, this is because of personnel, equipment frequent activities on the digging laneway base plate, adds disadvantageous natural conditions (as pore water, crevice water etc.), is difficult to like this make long-time existence of base plate observation stake.In addition, the method that at present the mine working deformation measurement is used is consuming time, take a lot of work and measuring result error larger.
Given this, overcome above-mentioned difficulties, researched and developed a set of new measuring system, native system can be convenient and swift and be accurately carried out the measurement of roadway deformation amount.
Summary of the invention
The object of the present invention is to provide a kind of coal mine tunnel top board deflection, two of can measuring to help the amount of shifting near, thereby grasp the coal mine roadway deformation rule, for safeguarding supporting measure that stability of the roadway is taked, provide coal mine roadway deformation measuring device and the measuring method of foundation.
Technical solution:
The present invention includes: the cover chi, ruler, cover chi one end is provided with plastic septum, and plastic septum is provided with magnetic base, in the cover chi, is inserted with ruler, and the cover chi is connected by slide rail with ruler, and the ruler external part is provided with magnetic base, and cover chi and ruler edge are respectively equipped with scale value.
Further: also comprise ring bolt and termination buckle measuring staff, measuring staff is provided with scale value.
Measure the method for roadway deformation with the coal mine roadway deformation measuring device, step is as follows:
1) help, on mid point highly, basic point A, B are set at a certain section two in tunnel, in section top board midpoint, lay measuring point C, stamp timber at A, B, C place respectively, be screwed into respectively the screw of termination band on timber;
2) measure the back deflection: the measuring staff of termination buckle is directly hung on the ring of roof station C screw, let go and allow measuring staff naturally hang;
3) at basic point A, B vertical pulling datum line, the scale numerical value of datum line and measuring staff intersection is the distance of roof station C to datum line AB, as initial value, and record; Adopt above-mentioned measuring method to measure and record the measurement data of gained each time;
4) roadway's sides shifts near the measurement amount, allows the cover chi one end in contact basic point A nail ring portion of tightening up a screw, and this end is fixed by magnetic base suction simultaneously; Ruler end stretches to wall basic point B screw ring portion, and this end is fixed by magnetic base suction simultaneously, and the scale value recorded on ruler is the roadway's sides width distance; Adopt above-mentioned measuring method to measure and record the measurement data of gained each time.
Advantage of the present invention:
1) basic point A, B are fixed in the end that will overlap respectively chi and ruler with identical tightening force that arranges in the time of can making at every turn to measure of magnetic base, and close contact, eliminate so as much as possible the error that the defect because of human factor or survey instrument itself causes, thereby improve measuring accuracy; In addition, the cover chi is connected by slide rail with ruler, and when idle, ruler is hidden oneself and overlapped in chi, is convenient for carrying.
2) termination buckle measuring staff and ring bolt supports the use the measurement that is very easy to the amount of crushing, only termination buckle measuring staff need be hung on the ring of screw and can be measured, each starting point of measuring is the termination hook portion of ring bolt ring portion and measuring staff, this starting point immobilizes, and so greatly improves measuring accuracy; In addition, the selection of measuring basis line only need be laid basic point at roadway's sides, and this basic point immobilizes, and is not subject to the impact of work in every and natural conditions in tunnel, thus measurement result accurately, reliable.
