Creating Micro Fractures in Rock Fragments for Blasting Efficiency Improvement

Abstract

Blasting is a commonly used method for rock fragmentation in mining operations for mineral extraction. It involves breaking the rock mass into small pieces, and ideally creating micro fractures within the small pieces. Such micro fractures could significantly reduce the energy required for subsequent processes like crushing and comminution. Additionally, micro fractures would enhance the rock-fragments fluid permeability thereby enhancing desired chemical reactions during certain processing operations.

This paper presents recent developments of the Multiple Blasthole Fragmentation (MBF) model, which simulates blasting rockmass fragmentation. The MBF model allows estimating rock strains experienced during the blast, for various blast design parameters and geometries. The intent is to correlate these strains with created micro fractures in the blast rock fragments. Adjusting blast design parameters in the MBF model of explosive loading and delay timing allows blast optimization. Such optimizing would create desirable strains to enhance micro fractures within the rock fragments. This would improve mining operations by enhancing downstream operation efficiency, thus reducing costs. Questions? Reach out regarding this presentation.

Global Energy Security Institute creates Equilibrium newsletter presenting “Energy in Context”.

November 30, 2023 —EPI is among those interviewed for their inaugural issue. (jump to EPI’s article here)

…Five articles begin the conversation: First an interview with former Israeli diplomat Ambassador Yuval Rotem on how Israel’s transformation from energy consumer to exporter affected its diplomatic and security policy.

Also included are contributions from Deputy Executive Director Dr. Rich Outzen and Director of Program Development Matt Yocum, as well as from noted energy experts Dr. Brenda Shaffer from the Naval Postgraduate School Energy Academic Group and Sidney Green, president and founder of Enhanced Production, Inc.

We hope you enjoy Equilibrium and look forward to your feedback and to continuing the global energy conversation at GEST 2024 in Tokyo! – Mike Nelson, Editor, Equilibrium

SPE presentation Pacing the Change of Energy – the US and Global

April, 2023

Presentation for the Salt Lake Chapter of Society of Petroleum Engineers April 18, 2023

Energy has the attention of the world, with developments rapidly progressing. Brief highlights and updates are presented on energy production and consumption, carbon emissions, and the transition from oil-gas-coal to renewable energies and carbon capture. Comments regarding energy availability and cost, and energy and minerals security facing the US as well as other nations and other broad conclusions are noted.

We continue focusing on research, engineering, and consulting-advising.

During 2018, EPI pursued improving the efficiency of hydraulic fracturing for the recovery of oil/gas from unconventional resources.

A technical presentation was given by Sidney Green at the 52nd US Rock Mechanics/ Geomechanics ARMA Symposium (www.epirecovery.com/news June, 2018) and an abstract has been submitted for presentation at ARMA 2019. Stay tuned for details.

Also during 2018, EPI continued development of the Geothermal Battery Energy Storage concept in collaboration with the Idaho National Laboratory and Prof. McLennan at the Univ. of Utah. Further funding for the concept is expected in early 2019 from the National Science Foundation via the Univ. of Utah with Co-Principal Investigators Prof. McLennan and Sidney Green.
