specific Embodiment approach

[0086] (1) On-site structural surface occurrence contact measurement, the process is as follows:

[0087] 1.1: Mine A slope and Mine B slope were determined through a graded analysis of a certain mine slope, taking mine A slope as the research object, measuring the height and width of the slope, and observing the development of rock mass structural planes within the research range general characteristics of

[0088] 1.2: According to the overall characteristics of the observed structural plane development, it is preliminarily judged that the rock mass of the slope is composed of k 0 Formation of structural planes, using a geological compass to measure the occurrence of each structural plane, the occurrence of structural planes includes dip A 0 and inclination B 0 , get at least 9 measuring point data;

[0089] 1.3: For structural surfaces whose inclination angles are all less than or equal to 80°, the occurrence data of each group of structural surface is based on the incli...

Abstract

The invention relates to a method for quickly and finely valuing slope rock mass joint orientation in open pit mines based on digital photogrammetry, which comprises the following steps: (1) contact measurement of field structural plane orientation; (2) fine measurement of structural plane digital photography; (3) data analysis and processing of the structural plane; (4) K means clustering and statistical analysis of the orientation of the structural plane. The method for quickly and finely valuing slope rock mass joint orientation in open pit mines based on digital photogrammetry in the invention adopts a digital photography measuring method to obtain the data of orientation of the structural plane, uses the K means clustering method to carry out grouping of the structural planes, determines a statistical distribution rule and a statistical feature value of orientation of each group of rock mass structural plane of the slope on the basis of statistical analysis of orientation of eachstructural plane and in combination with a field site measurement result and combines the field site investigation and indoor statistical analysis.

Description

technical field [0001] The present invention relates to a method for quickly and finely obtaining the occurrence of rock mass joints in an open-pit mine slope. In particular, the present invention obtains the occurrence data of the rock mass structural surface by using the digital photogrammetry method, and uses the K-means clustering method to carry out structure analysis. Based on the statistical analysis of the structural plane occurrences of each group, combined with the field measurement results, the statistical distribution rules and statistical characteristic values ​​of the rock mass structural plane occurrences of each group of slopes were determined, and the field survey was combined with the indoor statistical analysis. Combined, the reliability of determining the occurrence of rock mass structural planes on slopes in open-pit mines is significantly improved, and the invention belongs to the field of engineering technology. Background technique [0002] Structural...
