Gaining efficiencies and avoiding delays through well-planned surface water management
Monday, April 29 at 12:05pm
Presenter: Aytac Goksu
Surface water management has long been seen as a secondary side dish to an already full mining project plate. However, as any experienced professional will tell you, water has a way of making its importance to a project known. With an increased emphasis on risk management, stricter regulations, and added attention from investors, insurers and communities, water management is starting to get more attention early on. Building surface water into the decision-making process, including integration with engineering, will save unnecessary rework and avoid project delays.
This presentation will review which aspects of mine water management are required at different stages and outline the best practices that will benefit projects from initial development, through operations and closure. Learn about strategic surface water management planning that will help streamline permitting and gain efficiencies in schedule and budget.
Managing Occupational Hygiene Hazards Across Multiple Sites
Tuesday, April 30 at 11:15am
Presenter: Bryan Wilson
An increased focus is being placed on the health aspect of health and safety, and mining companies are actively looking to minimize worker exposures to hazardous environments in the workplace. Mining companies operating across multiple sites and regions often face the challenge of managing their worker exposures against differing regulatory jurisdictions and requirements. Occupational health and hygiene (OH&H) practices are important for minimizing these exposures. However, understanding the range of OH&H management practices that are being utilized at each site, as well as corporately, are critical to understanding the effectiveness of corporate policy in minimizing worker exposures to hazardous agents and meeting local regulatory requirements. This presentation will introduce an effective approach for conducting a baseline OH&H gap assessment of site level and corporate activities across multiple jurisdictions. Six key OH&H program elements will be discussed as well as best practice criteria for each element.
Mining Climate Change Case Studies and Planning for a Changing Climate
Wednesday, May 1 at 8:30am
Presenter: Rachel Wyles
The presentation will highlight a number of recent mining climate change case studies from various life of mine stages and across Canada. These case studies will demonstrate challenges of a changing climate and will highlight actions taken by mining companies to address these uncertainties. The presentation will summarize lessons learnt for future climate change adaptation planning in mining. The presentation will also provide an update on the Guidance for Climate Change best practices that Golder is developing for the Mining Association of Canada.
Soft Ground Tunnelling Techniques for Mine Access Development
Wednesday, May 1 at 8:55am
Presenter: Joe Anderson
The use of wet-mix structural sprayed concrete support has become increasingly prevalent in the tunneling industry over the last 50 years, being used to support both soft ground and hard rock conditions in temporary and permanent cases. In contrast, the mining industry has typically concentrated on using shotcrete, bolts and mesh as ground support in hard rock applications. However, applying techniques successfully implemented in tunneling was valuable when establishing a new hard rock development in South America where initial development through approximately 70 m of Saprolite and weak rock was required prior to driving 2 km of traditional hard rock drifts. Saprolite is a heavily weathered rock material, that behaves similarly to clay, and is common in humid and tropical climates. It inherits some of the relic structure of the decomposed rock, along which ground water flow can be highly variable. The material properties typically improve with depth prior to intersection with the fresh rock mass. The Sequential Excavation Method (SEM) was identified during the feasibility stages of the project as the most efficient and safe method of construction for the initial 70m development from surface, prior to transition into hard rock development. The final lining system was designed to accommodate long term ground loading as well as significant out of balance loads due to the weakness of the Saprolite material, low overburden, high ground water table and seismic activity. Prior to commencing tunnelling works, a cut and cover approach was used to establish a steel lined portal and provide an engineered face in which to start SEM tunnelling activities. This paper presents the design and construction considerations of the project, including discussions of the challenges met in implementing such a scheme in a remote location, with difficult ground conditions and with a hard rock mining team.
Overview of CIM’s Draft Guidance for Environmental and Social Disclosure under NI-43-101 Reporting
Wednesday, May 1 at 10:30am
Presenter: David Brown
The Environmental and Social Responsibility Society (ESRS) of the CIM undertook the development of a draft guidance document for Environmental and Social Disclosure of mining projects under National Instrument (NI-43-101), following a report by the Ontario Securities Commission which indicated significant disclosure deficiencies in this area. This session will feature presentation form the working group and will discuss the key areas that have been highlighted in discussions as needing improvement and will provide a suggested framework for future disclosure documents. An overview of key elements of environmental and social aspects of a mining project will be reviewed during the different phases of the project. This will be followed by a more detailed discussion of disclosure need around environmental studies and management, permitting and approval requirements, social and community aspects, and closure planning. This session will kick-off the consultation process that ESRS is planning to undertake on the draft guidelines for disclosure.
Speakers will include: Derek Riehm – Lundin Mining, David Brown – Golder Associates, Jenifer Hill – JLH Environmental, Alistair Kent – Merit Consultants, Richard Cook – Knight Piesold, Edith Garneau – Independent
