Problems solved by technology

When implementing directional drilling in coal mines, due to the large amount of data, it is required to be accurate and fast. If the traditional manual calculation and drawing methods are used, the speed is slow and difficult; if the existing measurement-while-drilling software is used, the storage format is single. Directly import the drawn trajectory map into the original electronic version of the geological plan, which cannot quickly realize the synthetic comparison between the measured trajectory and the designed trajectory

Abstract

The invention relates to a method for designing and drawing a directional drilling trace under a coal mine. When directional drilling is implemented under the coal mine, accuracy and quickness are required due to large data volume, but the conventional manual calculating and drawing method has the problems of low speed and large difficulty. The conventional measurement while drilling software cannot directly guide a drawn tracing image into the conventional electronic edition geological map due to single storage format, and cannot quickly realize composite comparison of an on-site measured trace and a designed trace. In the method, a horizontal projection length, E coordinates, N coordinates, a vertical depth, a measuring point elevation, version smoothness, a right deviation, global bending strength parameters and drawing data required by describing the directional drilling trace are acquired after processing by using an average angle range method and built-in functions in Excel. The designing and drawing of the directional drilling trace can be completed without special measurement while drilling software, calculation is accurate and quick, and storage formats are various; and the drawn directional drilling trace image is convenient for data exchange and sharing with other graphic software.

Description

Technical field [0001] The invention relates to a method for designing and drawing a directional drilling trajectory in a coal mine underground, in particular to a method for designing and calculating a directional drilling trajectory in an underground coal mine in Excel and drawing a trajectory diagram in AutoCAD. technical background [0002] At present, no one has been found to systematically study how to design and calculate the mine directional drilling trajectory in Excel, and draw the trajectory diagram in AutoCAD. When implementing directional drilling in a coal mine, due to the large amount of data, accuracy and speed are required. For example, the traditional manual calculation and drawing methods are slow and difficult; if the existing MWD software is used, the storage format is single. Directly importing the drawn trajectory map into the original electronic version of the geological plan can not quickly realize the synthetic comparison between the measured trajectory ...
