Western Canada Mine Rescue Manual Ministry of Energy and Mines Office of the Chief Inspector of Mines Western Canada Mine Rescue Manual Ministry of Energy and Mines Office of the Chief Inspector of Mines Victoria British Columbia Canada December 31, 1998 Revised 2014-15 This manuscript is for educational purposes only. Nothing herein is to be regarded as indicating approval or disapproval of any specific product or practice. 1-1 1-2 Foreword Every mine has to maintain a mine rescue team to help ensure the safety of workers and property on mine sites throughout B.C., Yukon, Northwest Territories and Nunavut. This manual has been crafted to demonstrate the basic equipment, procedures, practices, and principles that mine rescue trainees need to know before they respond to incidents at surface and underground mining operations. Mine Rescue teams have bravely responded to incidents and disasters throughout northern and western Canada for more than a century. It is through their training and practice that they have been able to come back safe and sound. Likewise, mine officials must also be familiar with their roles and responsibilities in the event of an emergency. Proper instruction must be complemented by individual and collective efforts to master the skills, equipment, and knowledge needed to execute a mine emergency response. This manual and training course represent the first steps you will take toward being able to answer that call. There are all sorts of incidents and emergencies that Mine Rescue teams can encounter, including electrical fires, gas leaks, avalanches, and motor vehicle accidents. Mine Rescue can be dangerous work, especially if it is not performed properly. Rescuers are responsible first for their safety and the safety of their team, but some responses will also require that they tend to casualties in need of assistance. In consulting the most up-to-date research as well as experts in government and industry, the committee who created this manual have endeavoured to make certain that the information found in these pages is as reliable, applicable, and above all, safe as possible. Your Mine Rescue training will not end when you finish this manual and course. Being a part of a Mine Rescue team means committing to a practice regime with your fellow Mine Rescuers to establish the cohesion, communication, and trust needed to function in the stressful environment of an emergency response. At times you may be called upon to assist in responses at other mining operations or to emergencies off-site. Wherever your Mine Rescue training takes you, wear the “MINE RESCUE” sticker on your hat with the pride and responsibility that it deserves.

It is located in a relatively undisturbed area of the boreal forest about 4 km off of Highway 914 and approximately 35 km north-northeast of the Key Lake uranium operation. Wheeler is a joint venture project owned by Denison Mines Corp. (Denison) and JCU (Canada) Exploration Company Ltd. (JCU). Denison owns 90% of Wheeler and is the operator, while JCU owns 10%. Denison is a uranium exploration and development company with interests focused in the Athabasca Basin region of northern Saskatchewan, Canada with a head office in Toronto, Ontario and technical office in Saskatoon, Saskatchewan. Historically Denison has had over 50 years of uranium mining experience in Saskatchewan, Elliot Lake, Ontario, and in the United States. Today, the company is part owner (22.5%) of the McClean Lake Joint Venture which includes the operating McClean Lake uranium mill in northern Saskatchewan. To advance the Project, Denison is applying an innovative approach to uranium mining in Canada called in situ recovery (ISR). The use of ISR mining at Wheeler means that there will be no need for a large open pit mining operation or multiple shafts to access underground mine workings; no workers will be underground as the ISR process is conducted from surface facilities.

  • WIPP Mine Rescue Teams: Ready to Save Lives Should and Emergency Arise
    . a critical step toward solving the nation’s nuclear waste disposal problem WIPP Mine Rescue Teams Ready to Save Lives Should an Emergency Arise Federal law requires every operating mine in the United States to have access to two mine rescue teams. Mine rescuers are highly- trained specialists with life-saving skills they hope they'll never need to use. The Westinghouse Waste Isolation Division, management and operating contractor for the U.S. Department of Energy (DOE) at the Waste Isolation Pilot Plant (WIPP), maintains two well trained, physically fit, and fully equipped mine rescue teams. In addition to rescue capabilities, WIPP’s Blue and Silver mine rescue teams support (and are supported by) personnel from area potash mines through Memorandums of Understanding. This ensures that mines in the same region have access to capable, highly-trained personnel in the event of an emergency. In the Beginning . The Early Days of Mine Rescue During the early 1900s, while investigating mine disasters and their causes, it was important and necessary to examine conditions in a mine as soon as possible after an explosion or fire. This need led to establishing mine-safety stations and rail cars. Although the original purpose of these stations and cars was to aid in technical studies and investigations, the courageous rescue work performed was so humanitarian and spectacular that the stations and cars soon were referred to as “mine-rescue” stations and cars. Stations and cars were equipped with mine-rescue and first-aid equipment, much of which in the beginning came from England and Germany.

Questions concerning this report can be directed to the Mine Safety Technology Task Force’s Technical Advisor, Randall Harris, at 304-558-1425 or [email protected] i Mine Safety Technology Task Force Report May 29, 2006 ABSTRACT The Sago and Aracoma disasters and their fourteen deaths, highlighted needed improvements in equipment, capabilities and processes for mine emergency response. The resultant worldwide attention has forever shifted the public’s view of underground mine safety. With the resolve of our government leaders, operators and labor representatives, we have embarked on a mission to improve mine health and safety, thus safeguarding the miners that fuel our nation. The Mine Safety Technology Task Force was charged with the duty of investigating and evaluating options and developing guidelines geared toward protecting the lives of our miners. Special emphasis has been placed on the systems and equipment necessary to sustain those threatened by explosion, fire or other catastrophic events while attempting escape or awaiting rescue. The West Virginia Mine Safety Technology Task Force Report provides a summary of commercial availability and functional and operational capability of SCSR’s, emergency shelters, communications, and tracking along with recommendations regarding implementation, compliance and enforcement.

  • Abandoned Mine Land Problems and Solutions in North Dakota
    Abandoned Mine Land Problems and Solutions in North Dakota William E. Dodd North Dakota Public Service Commission May 2002 About the North Dakota Public Service Commission and the Abandoned Mine Lands Division The Board of Railroad Commissioners was established by Dakota Territory in 1885. Its name was changed in 1940 to Public Service Commission (PSC) North Dakota has three Public Service Commissioners, each elected to six-year terms. The PSC has jurisdiction over electric and natural gas utilities, telecommunications companies, weights and measures, grain elevators, auctioneers, reclamation of mined lands, siting of energy plants and electric and gas transmission facilities, and railroads. The Commission has 41 full-time employees. The staff is divided into support services and five divisions that provide direct regulatory oversight and consumer assistance. The Abandoned Mine Lands (AML) Division administers a federal program to remove hazards associated with abandoned coal mines. The AML Division has 4.6 FTE’s. North Dakota’s AML Program was authorized in 1981 under the federal Surface Mining Control and Reclamation Act (SMCRA) of 1977. Program funding comes from a ten cent federal production tax on each ton of lignite coal mined in North Dakota. The state may apply for grants for half the production tax, or about $1.5 million per year. Since AML Program inception in 1981, $26 million have been spent to reclaim 100,000 linear feet of dangerous surface mine highwalls, 1900 acres of mine subsidence, and a variety of other hazardous abandoned mine features in North Dakota. An estimated $44 million more are needed to reclaim all remaining high priority AML Sites in North Dakota.
