A mine tunneling robot environment monitoring device and method

Abstract

The invention discloses a mine excavation robot environment monitoring device, which consists of a current excitation source, a telescopic protection cylinder, an electric rotation device, auxiliary cutting teeth, a cutting head entity, a transmission shaft, an optical fiber ring protective shell, an optical fiber ring, an optical fiber Composed of a current sensor control unit and a recovery electrode; the device will assist the current I e with monitoring current I d emitted into the coal seam, due to the auxiliary current I e with monitoring current I d The same-source currents are incompatible with each other, and the auxiliary current I e Squeeze monitoring current I d , so that the monitoring current I d Gather to monitor the environment of the front coal seam; part of the current emitted by the cutting head entity flows into the coal seam as the monitoring current I d , a part flows through the transmission shaft and the telescopic part of the roadheader as the return current I f , the fiber loop measures the return current I f , when the roadheader digs forward and encounters abnormal geological bodies such as water inrush and mud outburst, that is, the resistance of the coal seam changes, the measured backflow current I f There will be changes in order to detect the geological conditions ahead in real time.

Description

technical field [0001] The invention belongs to the technical field of coal mine monitoring, and in particular relates to an environment monitoring device and method for a mine driving robot. Background technique [0002] Coal resources are the most important energy resources in our country. In the process of coal production, roadway excavation is a particularly important part. However, due to faults, no carbon pillars, water gushing and other adverse geological conditions, the construction conditions of roadway excavation engineering are complicated. The roadway excavation environment is harsh, and accidents occur frequently in the roadway excavation work area. [0003] In order to adapt to the construction requirements of intelligent mines in my country, with the support of increasingly advanced excavation equipment and monitoring technology, the requirements for safe mining in coal mines are constantly increasing. In order to protect the personal safety of the majority of...
