basic types of point load tests: axial, diametral, and block or lump. The axial and diametral tests are conducted on rock core samples. In the axial test, the core is loaded parallel to the longitudinal axis of the core, and this test is most comparable to a UCS test. The point load test allows the determination of the
There are four main mining methods: underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.

Mineral Reserves are those parts of Mineral Resources which, after the application of all mining factors, are the basis of an economically viable project after taking account of all relevant processing, metallurgical, economic, marketing, legal, environment, socioeconomic and government factors.
riskmanagement structure has only in recent years been realized, mainly within the defense, construction and oil industries (Williams, 1995). The chapter explaines risk management processes through a research on mining project risks. For clarity, the chapter will start from explaining about mining projects, providing a simple process flow chart.
