Embodiment 1

[0025] A method for quickly evaluating the siliceous content of field shale, characterized in that it comprises the following steps:

[0026] (1) Place the outer cylinder of the measuring device horizontally, fix the electromagnet on the specified scale on the shaft, and energize the electromagnet to make the permanent magnet adsorb on the electromagnet;

[0027] (2) Select the first calibration rock block with known silicon content, the left end of the outer cylinder touches the surface of the first calibration rock block, change the direction of the current in the electromagnet, make the impact hammer pop out, hit the rock wall, and the probe measures the impact of the first calibration The impact sound frequency of rock blocks;

[0028] (3) Select the second calibration rock block with known silicon content, the left end of the outer cylinder touches the surface of the second calibration rock block, change the direction of the current in the electromagnet, make the impact h...

Abstract

The invention relates to a method for rapidly evaluating the siliceous content of field shale, the method comprises the following steps: horizontally placing an outer cylinder, fixing an electromagnet at a specified scale on a shaft, electrifying the electromagnet, and enabling a permanent magnet to be adsorbed on the electromagnet; selecting a calibration rock block with known siliceous content, enabling the left end of an outer cylinder to make contact with the surface of the calibration rock block, and changing the current direction in the electromagnet so that an impact hammer pops up and impacts a rock wall, and a probe measures the impact sound frequency of the calibration rock block; inputting the siliceous content of the calibrated rock block and the corresponding impact sound frequency into a display and calculation system; obtaining an associated equation of the siliceous content and the impact sound frequency through linear interpolation; repeating the second step for the vertical surface of the target rock block to obtain the impact sound frequency of the target rock block; and recording the impact sound frequency of the target rock measured by the probe, calculating by using the associated equation of the siliceous content and the impact sound frequency to obtain the siliceous content of the target rock, and displaying the siliceous content on the display and calculation system to realize rapid evaluation of the siliceous content.

Description

technical field [0001] The invention belongs to the field of geological engineering, and in particular relates to a method for quickly evaluating the siliceous content of field shale. Background technique [0002] In field geological exploration, the silicon content and shale content of rocks such as shale and slate are important parameters for the analysis of mineral composition in field outcrops, and are also the basic data for the analysis of reservoir sedimentary evolution, which is of great significance. [0003] Because shale, slate and other rocks with high silicon content are relatively hard, they will not undergo strong weathering when they are exposed to the surface, and often have obvious joints and sharp edges and corners. When the shale content is high, the outcrop rock samples are generally strongly weathered, with unclear edges and corners, and more micro-cracks and friable. At present, many indoor experimental equipment can accurately measure the silica and ...
