Abstract

The invention discloses a mine borehole radar fine detecting device based on drilling machine pushing and a detecting method thereof. A drilling machine, a drilling pipe, a non-metal drilling pipe, a borehole radar instrument, a non-metal drilling pipe, a drilling bit, a hole depth recorder and an explosion-proof mobile phone are included; the hole depth recorder is installed on the drilling machine to record the depth of the borehole radar instrument in drilling holes; the explosion-proof mobile phone communicates with the hole depth recorder and the borehole radar instrument, and time synchronization, parameter command issuing and transmission data issuing are carried out on the hole depth recorder and the borehole radar instrument; the borehole radar instrument comprises a control center module, a data storage module, a WIFI communication module, a battery, a trajectory measurement module, a transmitting antenna, a receiving antenna, a signal transmitter, a signal receiver and the like. The drilling holes in a coal mine can be detected, and the depth of the drilling holes being more than 500m can be detected, the interface position of a geological anomaly body, a water-containing anomaly body and a coal seam top and bottom plate within the range of 1m-10m on the periphery of the drilling holes can be detected, the resolution ratio is up to 0.15m-0.3m, and fine guidance basis is provided for intelligent mining in the underground coal mine.

Description

technical field [0001] The invention relates to the field of applied geophysical radar wave detection technology, in particular to a mining drilling radar fine detection device and method based on drilling rig push. Background technique [0002] With the development of intelligent mining in coal mines, the current coal mine exploration tends to search for small and hidden geological structures, the development of gas control and water damage control in coal mines from qualitative to quantitative, and the advanced detection needs of mining working faces. It meets the detection requirements of high detection accuracy and long detection distance. [0003] The general geophysical methods are carried out on the surface of the ground or the surface of the object to be measured. However, due to the complex structure of the underground or the interior of the object to be measured, only rely on the data obtained from these methods to accurately infer things such as lithology and geol...

Problems solved by technology

[0003] The general geophysical methods are carried out on the surface of the ground or the surface of the object to be measured. However, due to the complex structure of the underground or the interior of the object to be measured, only rely on the data obtained from these methods to accurately infer things such as lithology and geological body orientation. It is difficult to wait for information, which poses a new problem for geologists, that is, how to improve the accuracy of interpretation

However, the biggest feature and advantage of the radar in the well is high resolution and high precision, but unfortunately, the detection range is very limited, and the scale of the geological targets detected is also very small
