Drilling and measuring integrated experimental platform

Abstract

The invention relates to a drilling and measuring integrated experimental platform which comprises a traction device, a power device, a torque collecting device and an objective table, wherein a testblock is placed on the on the object table which is mounted on the traction device; the torque collecting device is separately connected to a motor and a drill pipe; and the drill pipe is aligned to the test block. The drilling and measuring integrated experimental platform provided by the invention can collect parameters such as torque, feeding force, diameter of the drill pipe, and drilling speed simultaneously and carry out real-time continuous monitoring, so that a phenomenon of missed report as effective information is missing by means of a method of drilling bits is avoided, the testingaccuracy is increased, and the safety of production operation is improved.

Description

technical field [0001] The invention relates to an experimental platform for researching the coupling relationship between parameters such as drill pipe torque and feed force and the mechanical properties of rock mass, in particular to an integrated drilling and measuring experimental platform, which belongs to the field of geological drilling. Background technique [0002] Preventing the occurrence of coal and gas outburst and rock burst is the key issue of underground safety production. Therefore, the determination of coal rock hardness and coal rock properties is extremely important. If the hardness and properties of coal rock cannot be accurately obtained, the gas in the coal seam and the energy stored in the coal rock layer will not only be unusable but also cause serious mine disasters and incalculable losses during the mining process.

AI Technical Summary

Problems solved by technology

If the hardness and properties of coal rock cannot be accurately obtained, the gas in the coal seam and the energy stored in the coal rock layer will not only be unusable but also cause serious mine disasters and incalculable losses during the mining process.

[0003] At present, coal mines use the drilling cuttings method to predict the risk of rock burst, but the collection index is single, resulting in low prediction accuracy; during the collection of drilling cuttings, it is easy to be blown away by the wind, which reduces the amount of drilling cuttings and is prone to errors

At present, there are relatively few experimental platforms for simulating the underground measurement of coal rock properties and coal rock strength.
