Abstract

The invention discloses a geological rock core space posture restoration device which comprises a base table, a rotary table rotationally arranged on the base table, a middle table body rotationally arranged on the rotary table and a rotary chuck rotationally arranged on the middle table body and used for clamping a rock core. The middle platform body is also provided with a displacement measuringdevice which can move along the rotation axis direction of the rotation chuck and is used for measuring the distance from the rotation axis of the rotation chuck to each point on the outer surface ofthe rock core; the rotation axis of the rotary table is perpendicular to the rotation axis of the middle table body, and the rotation axis of the rotary chuck is perpendicular to the rotation axis ofthe middle table body. The device has the characteristics of accurate restoration of the rock core space attitude, reliable parameter test precision and high automation degree, is suitable for original space attitude restoration of the common non-directional geological rock core, and assists in deep rock mass ground stress test and deep structure 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...
