System for the registration and analysis of low-frequency vibration accelerations of shaft lining in copper ore mining facilities
System Description
The shaft, as an underground structure, is subject to forces resulting from dynamic deformations of the surrounding rock mass. It is assumed that the shaft lining is tightly bonded with the rock medium (especially in the section of concrete lining embedded in compact and strong sandstones and Zechstein rocks) and fully transfers its vibrations, undergoing deformations with parameters determined by the vibration characteristics of the surrounding rock. In order to better assess the impact of seismic tremors on the shaft lining, measurements of vibration parameters have been initiated using accelerometric sensors mounted directly on the lining (tubing, lower and upper parts of the concrete lining).
The ARP 2000SZ system is characterized by a modular design that enables the implementation of distributed measurement networks. The system uses data transmission via mine fiber-optic networks. Three-component SSZ3X sensors are used in the system.
System Features
The ARP 2000SZ system consists of a station part and a field part. The station part is a PC computer, which serves as the main tool for collecting and processing measurement data. The field part includes local measurement concentrators with accessories, three-component shaft accelerometric sensors, shaft junction boxes, and optionally, a laptop for reading data from the concentrators. Up to 16 telemetry field sets (shaft measurement units) can be connected to the station part via fiber-optic cables.
