Many Canadian underground mines use longitudinal and transverse stoping with delayed backfill to extract tabular ore deposits. These methods require access to the orebody through a number of sill drives or cross-cuts which link the orezone to the haulage drift hence creating intersections on multiple levels. This study is the first to attempt stochastic methods with numerical analysis to mine developments for the purpose of evaluating their stability performance with respect to planned mining sequence. Consequently, a qualitative method is developed to estimate the risk level (e.g. rating and ranking) resulting from mining activity. Risk is the product of probability of failure and cost of consequences. A resultant assessment scale matrix (e.g., a 5-level risk index is derived which ranges from low to extreme) is then used to assign a risk index value which is directly proportional to the potential for excavation instability. The methodology is demonstrated through a case study (e.g., the No. 1 Shear East orebody at Vale’s Garson Mine in Sudbury, Ontario). Finally, the risk indexing tool can be used to confirm the need for enhanced supports and to compare alternative mine designs
Studies reveled that risk management practice has significant impact on the institution goal, mission and objective achievements. Although a risk mgt practice has been studied by some scholars, such types of studies are not made on the sector of cooperative. Thus the purpose of this study is to assess the Risk Management Practice of Saving and Credit Cooperatives Union. The study also come across major gap in practicing the risk mgt; the union doesn’t practice the risk mgt & risk mgt process is poor, there is no a department or individual personally responsible for risk mgt system, risk identification process is not going on a regular basis; qualitative risk analysis is not employed, standard tools and techniques were not used for identifying risk , there is no risk appetite and operational risk is the major risk that the union had confront. The researcher recommend, it is advisable for the union to have a department for risk mgt system, follow risk identification process to undertake it on a regular basis, Better to employ qualitative analysis, The management and control committee have to give emphasis for risk mgt and practical implementation of risk management.
