A measuring device and measuring method for the inclination angle of rock core fracture

Abstract

The invention relates to a rock core fracture surface inclination angle measuring device and measuring method. The device comprises an end cover with a circular opening, two guide rails and a base are bonded to the end cover, the base is located between the two guide rails, the other end of the base and the other ends of the guide rails are connected with an end plate, and the upper surface of the base is tangent to the circular opening formed in the end cover; the lower portions of two side plates made of a transparent material are connected with sliding blocks, the sliding blocks can freely slide on the guide rails, each side plate is provided with an arc-shaped dial used for measuring the angle, the corresponding center points of the two arc-shaped dials are connected through a pointer shaft, the pointer shaft is sleeved with a pointer, and the pointer can freely rotate around the pointer shaft. According to the rock core fracture surface inclination angle measuring device and measuring method, the defect that in an existing rock core fracture surface inclination angle measuring device, operation is tedious is overcome, the measuring process is greatly simplified, and meanwhile errors caused by the defects of the existing device are eliminated; in addition, the fracture surface inclination angle is measured by a surface-type pointer, and therefore the measuring precision can be significantly improved.

Description

technical field [0001] The patent of the present invention relates to a measuring device for the inclination angle of a rock core fracture and a measuring method using the device. Background technique [0002] Drilling technology must be used in human's research on the underground bottom layer and exploration of mineral resources, including underground prospecting drilling and stratum profile drawing. The main purpose of drilling is to analyze and record the extracted cores, so as to provide data reference and technical support for the development of various human geological activities in the future. Since the core has been rotated by an unknown angle relative to the original position during the extraction process, the inclination of the joint fractures contained inside the core cannot be accurately obtained, so only the angle between it and the drilling direction of the core can be taken. as the inclination angles of these fractures. The dip angle of core fracture and its...

AI Technical Summary

Problems solved by technology

At present, the measurement of the inclination angle of the core fracture is mainly the method of combining a protractor and a straightedge, that is, keeping the straightedge and the drilling direction of the core roughly in line, and using the protractor to measure the angle between the fracture surface and the straightedge. The straightedge is in an unstable state, so the result obtained in this way has a large error, which is not conducive to the true reflection of the actual situation
