The usage of telemetry measurements methods in order to determine shaft tube

Ensuring shaft’s safe operation is the primary aim of measurements and observations performed in mining shafts. This involves not only determining the current technical condition of the mining shaft, but also determining causes of observed changes. In order to preserve the efficiency of every shafts several inventory works have been performed, described in details in Ordinance (Regulation of the Minister of Economy from 28th of June 2002) and its appendix number 4 [1,2]. The report presents an overview of measurements techniques which are in use in order to perform shift tube’s inventory, with particular emphasis on telemetric measurement methods. As an example monitoring system designed for ‘Kościuszko’ shaft in ‘Wieliczka’ Salt Mine has been described in details. In order to prevent such situations, mobile system for monitoring the condition of the structure of the shaft was mounted and user in 2014 and 2015. Its indications allowed to define in the current time the value of deformation occurring in the shaft, and if necessary immediately modify the schedule and course of injection works. Analysis of the results shows a slight deformation of the shaft housing during the injection, and demonstrates the advantages of the monitoring system and a novel method of high-pressure injections.
