Slope stability and slope monitoring have become very common terms in opencast mines. Engineers, research scholars and scientists are inventing, innovating and publishing research articles on novel slope stabilization and slope monitoring ideas. The advent of Wireless sensors and IoT have drastically improved the standards of slope management. Considerably it has a major contribution to the cost reduction in the slope management system which lured small scale mining companies to adopt them. Although it is admirable that many mining firms have stepped forward to prioritize mine safety and embrace different wireless sensor networks (WSN) in slope management techniques, some flaws still exist that should be addressed. Many slope failures occur as a result of the collective influence of different aspects thus a combination of sensors that measures multi aspects of slope movement is indispensable. Acquiring acquaintance with several aspects of slope failure paves the way to enhance the slope monitoring system. So, in this paper, a detailed study of different factors affecting slope stability is discussed
