Abstract The article states the objectives of geotechnical monitoring in an open cast mine and discusses the main measurement methods. Distributed ledger technology (DLT) is recommended for monitoring and sharing data on the condition of the mine slopes between private and public organizations. Private DLT implementation is chosen because confidential corporate data is shared. A conceptual model for communication among the Mining Company, the responsible institutions and regulatory authorities has been suggested. It has been established that there is a possibility of leakage of personal data according to the GDPR.

A new tool for achieving a sustainable business climate in mining is DLT communication and blockchain data recording. The introduction of DLT will help increase confidence among participants mining executives, employees, regulators and suppliers. The factors that interdict the implementation of DLT are classified. Each of them has been analyzed and models for data exchange among roles have been proposed for illustration. The example is for measurement of the energy consumed and the material mined for an open pit. A scheme for the introduction of correction in case of measurement unaccuracy has been developed.

The article describes the advantages provided by the implementation of a directed acyclic graph in the blockchain network. The advantages and known limitations of common blockchain networks are described. It is shown how directed acyclic graph allows increasing the speed of transactions between the network nodes and scaling the channel width due to the formation of parallel chains instead of the single true chain in common blockchain networks. Consequently, it is shown how blockchain network with directed acyclic graph also eliminates the concept of mining, allowing for transactions without the corresponding fees.
