Mine tunneling robot environment monitoring device and method

Abstract

The invention discloses a mine tunneling robot environment monitoring device. The device is composed of a current excitation source, a telescopic protection cylinder, an electric rotating device, auxiliary cutting teeth, a cutting head entity, a transmission shaft, an optical fiber ring protection shell, an optical fiber ring, an optical fiber current sensor control unit and a recycling electrode. According to the device, auxiliary current Ie and monitoring current Id are emitted into the coal seam, the auxiliary current Ie extrudes the monitoring current Id due to the fact that the auxiliary current Ie and the monitoring current Id are homologous currents and are incompatible, and the monitoring current Id is gathered to conduct environment monitoring on the front coal seam. A part of current emitted by a cutting head entity flows into a coal seam as monitoring current Id, a part of current flows through a transmission shaft and a telescopic part of the heading machine as backflow current If, the backflow current If is measured by an optical fiber ring, when the heading machine advances forwards and encounters abnormal geologic bodies such as water inrush and mud inrush, namely, the resistance of the coal seam is changed, the measured backflow current If can change, and the monitoring current Id and the backflow current If are monitored. Therefore, the front geological condition can be detected 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...
