Description
Technical field
The invention belongs to coal mine roadway e measurement technology, more particularly to a kind of roadway surrounding rock two help and roof deformation amount it is real-time
Measurement apparatus and measuring method.
Background technology
With the continuous development of coal in China technology, solve many technical barriers on many collieries.But with adopting
Deep is continuously increased, China just progressively step into the deep mining stage, and deep mining has high-ground stress, high/low temperature and Gao Yan
The features such as molten hydraulic pressure, these features will cause the increasingly exacerbation of surrouding rock deformation.Therefore understand fully the deformation rule of roadway surrounding rock for
The stress distribution law of roadway surrounding rock and the determination of roadway support scheme are most important.
At present, the measurement rock deformation equipment main in China mining survey field has：Tape measure, measuring staff, sensing device
Deng.There is the deficiencies of measurement accuracy is low, measurement difficulty is big, accuracy is poor part using tape measure, it is most important that lane can not be measured
The amount of shifting near and deflection of road country rock；Although it can be measured using measuring staff in each measuring point of roof and floor, weak point
It is to need more people to coordinate when measuring, can only measure the amount of shifting near of a measuring point every time, being commonly used for measuring staff can cause measuring staff
The loosening of sleeve and the abrasion of measuring staff scale, this will cause to produce larger error during reading.Therefore measuring staff measurement has labor intensity
Greatly, the shortcomings of scope of application is low, measurement error is big；Using sensing device because sensing device is complicated, volume is big, weight
In place of the deficiencies of heavy, inconvenient to carry, these will influence the normal production of working face.
The content of the invention：
The technical problem to be solved in the present invention：A kind of roadway surrounding rock two is provided to help and the real-time measurement apparatus of roof deformation amount and survey
Amount method, with solve prior art heading country rock two is helped and roof deformation measurement existing for measurement accuracy it is low, measurement
Difficulty is big, accuracy is poor, weight is not easy to greatly the technical problems such as carrying.
Technical solution of the present invention：
A kind of roadway surrounding rock two is helped and the real-time measurement apparatus of roof deformation amount, and it includes Telescopic measuring ruler and slide rail, slide rail
The left and right sides is fixed with expansion link, is fixed with telescopic supporting rod between two expansion link tops, on expansion link and telescopic supporting rod
It is fixed with Telescopic measuring ruler.
Two expansion link bottoms are fixed with pulley, and the pulley is arranged in slide rail.
The Telescopic measuring ruler includes jam, and spring and shrinkage-rule, spring at least two rows, spring are fixed with jam
Pad is fixed with shrinkage-rule top.
A kind of described roadway surrounding rock two is helped and the measuring method of the real-time measurement apparatus of roof deformation amount, and it includes：
Step 1, the bottom that slide rail is fixed on to tunnel to be measured；
Step 2, the pulley of two expansion links is put into slide rail and fixed block；
Step 3, the both ends of telescopic supporting rod and the top of two expansion links are fixed；
Step 4, the jam of each Telescopic measuring ruler is fixed on telescopic supporting rod and expansion link；
Step 5, the pad of Telescopic measuring ruler contacted with coal seam to be measured.
Beneficial effects of the present invention：
The present invention can install fixed Telescopic measuring ruler according to the deformation and tested point in tunnel, and rational in infrastructure, technology can
OK, easy to process, flexibility is high, and the device can at any time be dismantled and avoid the wasting of resources；In addition, the device volume is small, carrying side
Just, cost is low, is easy to promote and implements, and is the innovation on mine and tunnel survey instrument, has good economy and society's effect
Benefit；Solve prior art heading country rock two is helped and roof deformation measurement existing for measurement accuracy it is low, measurement difficulty
The technical problems such as greatly, accuracy is poor, weight is not easy to carry greatly.
