A system and method for measuring the true dip and true direction of rock strata

Abstract

The present invention provides a system and method for measuring the true inclination angle and true direction of a rock formation. The system includes: a laser, an inclination measuring device, a direction measuring device, and a processor; the laser is connected to the inclination measuring device and the direction measuring device respectively , the processor is respectively connected with the inclination measuring device and the direction measuring device. The method includes: measuring the first apparent inclination and the first apparent trend of the intersecting line between the rock formation to be measured and one side of the roadway; measuring the second apparent dip and the second apparent direction of the intersection line between the rock layer to be measured and the other side of the roadway; Measure the first apparent inclination and the first apparent direction of the intersecting line between the rock formation and one side of the roadway, the second apparent inclination and the second apparent direction of the intersection line between the rock formation to be measured and the other side of the roadway, and solve the true value of the rock formation to be measured. dip and true direction. Through the trend and dip of any two non-parallel straight lines on the rock layer, the true dip and true trend of the rock can be quickly measured and calculated. The method is simple, convenient, accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of engineering geological exploration, in particular to a measurement system and method for the true inclination and true direction of rock formations. Background technique [0002] In the prior art, in coal mining roadways and engineering tunnels, it is usually obtained by directly measuring on the rock layer by means of a geological compass. The specific method is as follows: First, adjust the pointer of the horizontal bubble of the geological compass to 0°, then stick the long side of the compass on a complete and smooth layer of the rock formation, move the compass slowly to center the horizontal bubble, and Draw a line on the long side, this is the strike line of the fault, and the direction of the rock formation can be known according to the strike line. Second, align the short side of the compass with the line drawn and center the horizontal bubble, brake and read the pointer, which is the inclinatio...

AI Technical Summary

Problems solved by technology

[0003] However, in the actual engineering of coal mining roadways and engineering tunnels, there will be many problems. Using a geological compass to measure the inclination and direction, and adjusting the water bubble of the level to center each time, not only the method is cumbersome, but also the work efficiency is relatively low. In fact, there is often a lack of exposed rock layers or faults, and it is often inconvenient to use a geological compass. In addition, the application of construction machinery and metal support materials seriously affects the accuracy of the compass, making it increasingly difficult to measure the real parameters of rock layers or faults.

If the wire-rope measurement method is used, it requires many people, takes time, and takes up a lot of space. It interacts with the mining work, and there are many measurement links, so the error is also large.
