Problems solved by technology

For example, using the paleomagnetic method to restore the attitude of cores is limited to sedimentary rocks; using acoustic-electric borehole imaging technology to restore cores in the later stage, this method has complicated testing procedures and is difficult to operate in practice; in addition, there have been non-oriented rocks The actual accuracy of the core ground orientation method needs to be further improved

Abstract

The invention discloses a geological rock core spatial attitude recovery device, which comprises a base platform, a rotatable turntable arranged on the base platform, a rotatable intermediate platform body arranged on the turntable, and a rotatable intermediate platform arranged on the intermediate platform. The rotary chuck on the body is used to clamp the rock core; the intermediate platform is also equipped with a displacement along the axis of rotation of the rotary chuck to measure the distance from the axis of rotation of the rotary chuck to the outer surface of the core. Measuring device; the rotation axis of the turntable is perpendicular to the rotation axis of the intermediate platform, and the rotation axis of the rotary chuck is perpendicular to the rotation axis of the intermediate platform. The present invention has the characteristics of accurate restoration of rock core spatial posture, reliable parameter testing accuracy and high degree of automatic assembly, is suitable for restoring the original spatial posture of ordinary non-directional geological rock cores, and assists in deep rock mass stress testing and deep structural analysis.

Description

technical field [0001] The invention belongs to the field of deep geological rock core testing equipment, and in particular relates to a geological rock core spatial attitude restoration device. Background technique [0002] With the increasing demand for mineral resources and the continuous consumption of shallow resources, the development of my country's future mineral resources will fully enter the deep deposits within the second depth space (1000-2000m), and deep mine mining will become the norm. Deep geological core has become an important basis for understanding various physical and mechanical properties, structural and structural characteristics, mineral composition and grade, rock thickness and buried depth of deep underground rock mass. [0003] However, since most of the cores are non-directional cores obtained from ordinary geological drilling, the original spatial attitude of the cores cannot be known, which greatly limits the effective use of deep cores. For ex...
