Geological detection system for horizontal drilling machine

Abstract

The invention provides a geological detection system for a horizontal drilling machine. The geological detection system comprises a corer, a pipeline robot, a camera system and detection equipment, wherein the corer and the pipeline robot are arranged in a coring channel, and the camera system and the detection equipment are carried on the pipeline robot. The pipeline robot comprises a robot body, a motor, a driving assembly and a coring clamp, wherein the motor, the driving assembly and the coring clamp are arranged on the robot body; the robot body is of an octahedral column structure and is connected with a winch through a steel wire rope; the motor is connected with the driving assembly and matched with the steel wire rope and the winch to achieve free movement of the pipeline robot in the coring channel; the coring clamp is used for grabbing the corer; the driving assembly comprises a plurality of driving wheels. The distance between the driving wheels and the robot body is adjustable; the pipeline robot, the camera system and the detection equipment each comprise a wireless communication module; and a plurality of repeaters are distributed on the steel wire rope at intervals to ensure signal transmission. By means of the geological detection system, efficient coring and surrounding rock recognition at an ultra-long horizontal distance can be achieved, the prediction precision is high, and signal transmission is stable.

Description

technical field [0001] The invention relates to the technical field of geological engineering, in particular to a geological detection system for a horizontal drilling machine. Background technique [0002] In the process of exploration and development of mineral resources (including solid ore, liquid ore, gas ore, etc.), a drilling rig is a mechanical device that drives a drilling tool to drill underground to obtain physical geological data. It can be used to drill rocks. Cores, ore cores, cuttings, gaseous samples, liquid samples, etc., to ascertain the conditions of underground geology and mineral resources. [0003] Before TBM (Tunnel Boring Machine, full-face hard rock tunnel boring machine) and drill and blast construction excavate the tunnel, it is necessary to forecast the geological conditions in advance and find abnormal conditions in time. By predicting the position, occurrence and integrity of surrounding rock structure and the possibility of water content of un...

AI Technical Summary

Problems solved by technology

[0005] In summary, the existing advanced geological drilling methods have the following problems: 1) The prediction effect is poor under complex geological conditions, and it is difficult to predict the small faults and penetrating large joints in front of the face of the main tunnel, especially when it is connected with the tunnel. For parallel structural planes, the prediction is basically invalid; 2) It takes a long time for construction work and the detection distance is limited. Rock cores are used to judge the geology, and surrounding rock conditions such as cavities and water accumulation cannot be identified. The confidence in the detection of surrounding rock formations and the analysis of the overall situation is not high
