Embodiment Construction

[0034] figure 1 It is a schematic diagram of the acquisition and calculation method of rock formation parameters provided in Embodiment 1 of the present invention.

[0035] Embodiment 1 of the present invention provides a method for acquiring and calculating rock formation parameters. By using the above method, rock formation parameters and fault occurrence parameters can be obtained, and the principle is the same. Wherein the method comprises the following steps:

[0036] Step 11, obtaining the pseudo-dip angle of the rock formation at the side of the roadway and the pseudo-dip angle of the rock formation at the front section.

[0037] The analysis methods for the occurrence parameters of faults and rock formations are the same. In this application, the acquisition of the occurrence parameters of rock formations is used as an example for description, but it is also applicable to the acquisition of fault occurrence parameters. The pseudo-dip angle of the rock formation at th...

Abstract

The invention provides attitude of bed parameters acquisition and calculation methods which include the steps of acquiring a pseudo dip angle of a wall of rock stratum of a roadway and a pseudo dip angle of a head-on profile rock stratum; acquiring an initial position of the exposed rock stratum on the roadway wall; calculating to obtain a rock stratum forming direction, an inclined direction and an inclined angle through a drawing technique according to the initial position, the pseudo dip angle of a wall of rock stratum of the roadway and the pseudo dip angle of the head-on profile rock stratum. By the above attitude of bed parameters acquisition and calculation methods, the certain pseudo dip angle of a wall of rock stratum of the roadway, the certain pseudo dip angle of the head-on profile rock stratum and the certain initial position of the exposed rock stratum on the roadway wall can be easy to measure according to the actual production, the attitude of bed can be calculated to get by the drawing technique, so that a geological compass can be avoided being used in the complex environment, collection and collation of geological data in the mine engineering and tunnel engineering are more secure, high-efficient, and the manpower cost and the time cost which are needed in measurement are saved, and the attitude of bed parameters acquisition and calculation methods have a positive significance for practical popularization.

Description

technical field [0001] The invention relates to the field of collection and analysis of geological data in shaft engineering and tunnel engineering construction, and in particular to a method for acquiring and calculating rock layer occurrence parameters. Background technique [0002] In the construction process of shaft engineering and tunnel engineering, the roadway is constructed in rocks, and most of the rocks are layered and distributed in layers. Continuous, rock formation or fault occurrence parameter, essentially refers to the spatial distribution direction of the rock formation or fault level, the analysis of the spatial distribution direction of the rock formation or fault can predict whether there is a construction safety threat ahead of the roadway. The occurrence parameters of a fault (or rock formation) mainly include the strike, dip and dip of the fault (or rock formation). Wherein, the rock formation trend refers to the extension direction of the intersectio...
