Abstract

The invention discloses a coal mine fully mechanized mining face advancing degree detection system and method. The coal mine fully mechanized mining face advancing degree detection system is composedof positioning anchor points, positioning tags, positioning controllers, a master control system and the like. The positioning anchor points are fixedly installed on the rock walls of an air intake roadway and an air return roadway at equal distances, the positioning tags and the positioning controllers are deployed on a hydraulic support, a coal mining machine and the like, the distances betweenevery two positioning nodes are measured, distance measurement data are transmitted to a main control computer by the positioning controllers through communication network, the positions of the equipment in the mining face advancing process are worked out by the main control computer according to the data, and therefore automatic detection can be achieved in the mining face advancing process.

Description

technical field [0001] The invention relates to a detection system and a detection method of a coal mine fully mechanized mining face, in particular to a system and a method for realizing the detection of the advance degree of a fully mechanized mining face by short-distance positioning and distance measurement. Background technique [0002] In coal mines, the advance degree of fully mechanized mining face can not only reflect the speed of advance of the working face, but also the main parameter for the assessment of the work results of the fully mechanized mining team. In the current practical application, the detection of the advancing degree of the working face is mainly through the method of manual recording by the underground workers. Circumstances, and then there will be a certain deviation between the calculation results and the actual situation. Therefore, a fully mechanized mining face advancement detection system can be used to detect the advancement of the entire...
