Taylor, Titan Mining c. kling; BQ Energy, Darien, CT __________________________________________ Brownfield sites such as reclaimed strip mines and landfills can be great 2:00 PM locations for solar parks and wind farms. These renewable energy projects Introductions can provide mining companies with a combination of energy supply and independence, annual land lease payments, capital investment and 2:05 PM renewable energy credits. Permitting can be compatible with closure Global Financing of Coal-Fired Power Projects permits with minimal impacts to the surface. M.

Monday, February 24 Afternoon 2:35 PM What are you token about? Tokenizing a Mining Royalty or Stream to Raise Non-Equity and Non-Debt Financing 2:00 PM • North 225B N. Johnson, J. Deem and A. Cohn; Bailey & Glasser LLP, Washington, DC The appetite of large institutional investors for mining projects is waning, and most Coal & Energy: Best of Ground Control especially so for fossil fuels projects. In addition to activist pressure to defund Chairs: M. Murphy, National Institute for Occupational mining, returns have been disappointing. Enter tokenization. Blockchainbacked digital financing tools such as tokenization are democratizing mining project Safety and Health, Pittsburgh, PA T. Klemetti, NIOSH, finance. This submission will focus on the legal framework and hurdles to token- Pittsburgh, PA financed mining projects. Must you register with an exchange? What are the __________________________________________ disclosure requirements? Will you bust a covenant in your debt stack? Will it breach your leases? We will explore the fundamental background of tokenization 2:00 PM and provide a framework for answering these questions. Introductions 3:05 PM 2:05 PM Coal - Industry and Financing Trends, Alternatives and Assessing Risks from Mining-Induced Ground Movements Near Possibilities in the Current Market and the Future R. Gas and Oil Wells Reeves; Northcott Capital, Denver, CO G. Rumbaugh and C. Mark; Mine Safety and Health Administration, This presentation will provide an update of the landscape and market for raising Pittsburgh, PA capital. It will start with a brief overview of competing energy sources together with The proliferation of unconventional gas well development in the Northern coal, and discuss recent developments in the coal industry both nationally and Appalachian coalfields has raised a number of mine safety concerns. internationally that are relevant for financing at the mine and corporate level. The Unconventional wells, which extract gas from deep shale formations, are discussion will focus on financing alternatives for a mature industry and explore characterized by gas volumes and pressures that are significantly higher than possible alternatives or scenarios that could create upside for the industry and facilitate raising capital. The discussion of upside will be intended to stimulate the those observed at many conventional wells. The gas is composed largely of audience to consider alternative markets for coal as a fuel. methane as well as other hydrocarbons. Hundreds of planned and actively producing wells penetrate protective coal pillars or barriers within active mine boundaries, including chain pillars located between longwall panels. Gas released 3:35 PM from a well damaged by mining-induced ground movements could pose a risk to The Future of Uranium R. miners by flowing into 2 SMENET 2020 annual meeting the mine atmosphere. McCormick; Energy and Natural Resources, Capstone Headwaters Investment The mining-induced ground movements that may cause well damage include Bank, Dallas, TX All eyes will be on the Uranium Mining Industry as a production shortage should conventional subsidence, non-conventional subsidence (e.g. bedding plane slip), drive Uranium prices up rapidly in the next 9-12 months or so. This shortage is pillar failure, and floor instability. This paper describes the known risk factors for due to increased construction of nuclear power plants and 8 idled plants in Japan each of the four failure mechanisms. It includes a framework that can guide the coming back on line with a total of 15 shuttered plants approved for restart. In risk assessment process when mining takes place near gas or oil wells. addition, Kazakhstan (40% of the world’s production) and Canada, two of the leading U3O8 producers, both made drastic production cuts during the last two years. There are a total of 451 nuclear power plants currently in operation in some 30 countries. Add to that 69 nuclear power plants currently under construction 2020 | TECHNICAL PROGRAM 1 2:25 PM than 200 m, the abutment angle was found to be significantly less than 21°. Investigations of Longwall Mining Subsidence Impacts on In this paper, a new equation employing the panel width to overburden depth Pennsylvania Highway Alignments ratio is constructed for the calculation of accurate abutment angles for deeper E. Adelsohn, A. Iannacchione and R. Winn; University of Pittsburgh, mining cases. Pittsburgh, PA Over 600 longwall panels have been mined in the last 50 years, with 24 panels 3:25 PM under interstates in Pennsylvania alone. The Gateway, Emerald, and Cumberland The Development of a Multiple Level Underground Limestone mines undermined I-79 with 17 panels between 1982-1989 and 2003-2008 Mine from Geology through Mine Planning respectively; Mine Eighty-Four undermined I-70 with 4 panels between 1987- C. Newman1, D. Newman1 and R. Dupuy2; 1Appalachian Mining & Engineering, 2000. Through the examination of the panels that undermined I-70 and I-79, Lexington, KY and 2Rogers Group, Inc., Nashville, TN it is possible to determine which factors have most impacted the highway The development of a multiple level underground mine is a complex task in which alignments. In some locations, the highway intersects with panels at angles geology, engineering, ground control, and unit operations are integrated into a single ranging from 45 to 80 degrees, and at others, it runs between two panels, mine design. The components are inter-dependent and must function cohesively which simulates the effect of gateroads on the subsidence. The panels width to ensure a profitable underground mining operation. To optimize reserve recovery, to overburden ratio varies between 0.64 and 1.7, meaning that the interstates mine planning should begin from the lowest level and progress up. This limits any were influenced by both subcritical and supercritical subsidence basins. The misjudgments or oversights of a given level affecting the underlying levels and face advance rates and overburden depths also vary between the panels. The ensures the ability to maximize recovery from each level. The process and the effects of subsidence on the surface from these panels were recorded over decisions are presented through case history examples. The theme is that there the years. Using the Surface Deformation Prediction System, models were is one opportunity to “get it right” and many chances to overlook a small aspect developed to relate the effect of overburden, panel size, orientation of the road, within the design of multiple level underground stone mines that will plague the mine throughout all level and through the entirety of its operating life. and rate of mining to the subsidence impacts on the highway. 2:45 PM 3:45 PM Evaluation of Stress Control Layout at the Subtropolis Mine, Understanding Roof Deformation Mechanics and Parametric Petersburg, OH Sensitivities of Coal Mine Entries Using the Discrete A.
