Effect Of Mining And Geology On Mining-Induced Seismicity – A Case Study, Heba Khalil, Tuo Chen, Yu-Hang Xu, Hani Mitri
Journal of Sustainable Mining
Mining-induced seismicity is a commonly occurring phenomenon in underground mines. This poses a greater challenge to the safety of the mining operation. This paper presents a case study of the Young-Davidson mine in northern Ontario, Canada, where seismic events of magnitude Mn 2.0+ have been observed at mining depths of 600 to 800 m below the surface. The occurrence of large seismic events at such shallow depths is the key issue of this study. A comprehensive study of the microseismic database has been conducted to discern the root causes for the unusually strong seismic activities recorded at shallow depths. The …
Use Of Insar In Linear Discontinuous Ground Deformation Generation Analysis: Case Study Of A Mine In Poland, Bartosz Apanowicz
Use Of Insar In Linear Discontinuous Ground Deformation Generation Analysis: Case Study Of A Mine In Poland, Bartosz Apanowicz
Journal of Sustainable Mining
Linear Discontinuous Ground Deformations are defined as fissures and steps, as well as structural forms composed of them. They occur on the surface as a result of underground mining. Knowledge of LDGDs has been acquired through field observations which are subsequently described in the scientific publication. Records of LDGDs are made by using the classic surveying method. The paper reviews the created LDGDs in the years 2015–2019 in one of the mines of the USCB. The analysis covers the velocity of subsidence as a result of underground mining and the values of horizontal strains determined according to the Knothe-Budryk theory. …
The Use Of Microalgal Sourced Biodiesel To Help Underground Mines Transition To Battery Electric Vehicles, Corey A. Laamanen, Kyle Moreau, Sabrina M. Desjardins, Shannon H. Mclean, John A. Scott
The Use Of Microalgal Sourced Biodiesel To Help Underground Mines Transition To Battery Electric Vehicles, Corey A. Laamanen, Kyle Moreau, Sabrina M. Desjardins, Shannon H. Mclean, John A. Scott
Journal of Sustainable Mining
The use of fossil fuel sourced diesel underground has various associated health and environmental hazards, and additional energy demand and costs associated with necessary ventilation. One way to reduce these impacts is by utilizing a biodieselblend, which generates lower levels of harmful emissions from underground equipment and can be produced regionally, reducing the impact of transportation. Furthermore, this would help allow use of existing machinery during transition towards more widespread electrification underground. Therefore, the concept of an integrated supply and use chain within the mining industry is examined based on biodiesel from acidophilic photosynthetic microalgae cultivated using CO 2 in …
