Construction and accuracy analysis of the automatic monitoring system for coal mining subsidence
Combining with the characteristics of the coal mining subsidence monitoring, the automatic monitoring system for coal mining subsidence is introduced from the system construction and composition of system in this paper.The system is based on GNSS CORS technology, GIS technology, computer network communication technology, mobile PDA technology, modem measurement data processing technology.It takes GNSS reference station subsystem, GNSS CORS monitoring station subsystem, data monitoring center subsystem and subsystem of communication as core modules.Equipment monitoring, data collecting and transmitting, data processing and analyzing, subsidence predicting, mining damage evaluating are built up into a automatic monitoring system for coal mining subsidence.This system can provide decision-making basis for mine safety mining and geological environmental governance.Using real-time measurement data in the system, the monitoring accuracy of the system is analyzed, and the results show that the planar measurement accuracy can be up to±5 mm, height measurement precision can be up to ±7 mm.These accuracy can meet the accuracy requirement of mining subsidence monitoring.
