Hole drilling cableless detection system for mines

Abstract

The invention relates to the technical field of mine detection, and provides a hole drilling cableless detection system for mines for hole drilling detection. The hole drilling cableless detection system has the specific technical scheme that the hole drilling cableless detection system for mines disclosed by the invention comprises an upper computer and a host in communication connection, whereinthe host is respectively connected with a detecting pipe and a depth finder; the detecting pipe comprises a video signal processing control circuit board, an azimuth angle measurement integrated circuit board and a signal processing circuit board which are respectively connected with a parameter acquisition control circuit board; the parameter acquisition control circuit board is connected with abattery pack; the battery pack is connected with a voltage stabilization protection circuit board; the video signal processing control circuit board is connected with a camera; the azimuth angle measurement integrated circuit board is connected with a three-axis tilt angle sensor and a three-axis azimuth angle sensor; and the signal processing circuit board is connected with a natural gamma probe. The hole drilling cableless detection system for mines disclosed by the invention has the advantages that the hole drilling depth, the geological structure and the hole drilling track can be simultaneously detected, and the operation is convenient.

Description

technical field [0001] The disclosure relates to the technical field of mine detection, in particular to a cableless multi-parameter combined detection system for detecting mine boreholes. Background technique [0002] Gas, water inrush, coal dust, roof collapse, fire and other unsafe hidden dangers in coal mines, among which gas and water inrush are the two most unsafe major hidden dangers, and unsafe gas drainage is the root of preventing and controlling coal mine gas disaster accidents Measures, since the 1950s, my country has promoted gas drainage as an important measure to control coal mine gas disasters in high-gas and outburst mines; In 2006, it was clarified again that the control of coal mine gas must be adhered to, and the gas drainage must be drilled first, and then the gas must be discharged through the drill hole. After years of hard work, my country's coal mine underground drilling technology And equipment has a great development. [0003] However, on the one ha...

Problems solved by technology

[0003] However, on the one hand, the diversity of geology and coal seams in my country and the cultural quality of coal miners are generally not high, resulting in the drilling depth, inclination angle, and azimuth angle not meeting the design requirements, resulting in unclean gas drainage and gas discharge during drilling. Unfavorable geological bodies (subsidence column, karst collapse hole), on the other hand, there is no coal mine downhole logging instrument specially used to simultaneously detect drilling depth, geological structure and drilling trajectory in the industry, which makes the drilling depth of coal mine gas The management and prevention of water brings certain difficulties, which has buried certain hidden dangers for future safe production, and seriously restricts the safety production efficiency of my country's coal mining industry.
