Safe handling procedure for dump (overburden) 1. The overburden (O.B.) shall be dumped at a distance of 3.5 m from the edge of the O.B. dump and the dozer shall push the same O.B. 2. Operators shall not drive their vehicles into the “non-operational area” which is designated by a berm of a minimum height of 1.5 m. 3. Operators shall not drive their vehicles on unstable surfaces or edges which are designated by flag posts, signs etc. to warn. 4. On entering the O.B. dump, the dumper/tipper operator shall visually inspect the general area of ​​the O.B. dump. All due care shall be taken by the dumper/tipper operators regarding the position of the rear wheels of the dumper/tipper on the dumping face. The dumper/tipper operator shall not reverse the dumper/tipper into an area which he has not visually inspected. 5. When dumping is done in an area where no berm exists, the O.B. shall be dumped before any edge which shall be pushed into position by the dozer and shall be constantl...

Rock failure theories:-  Rock failure can occur due to various factors and can be explained by several theories. Here are some of the commonly accepted theories of rock failure:- 1. Mohr-Coulomb Theory:- This theory is widely used to understand the failure of rocks under different stress conditions. It is based on the concept of shear strength and assumes that failure occurs when the shear stress exceeds the shear strength of the rock material. The Mohr-Coulomb theory considers the cohesive strength and frictional strength of rocks in determining failure.   2. Griffith Theory:-  This theory, also known as the linear elastic fracture mechanics theory, focuses on the failure of rocks due to the presence of pre-existing cracks or flaws. It suggests that failure occurs when the stress intensity factor at the tip of a crack exceeds a critical value. The theory considers the elastic properties of the rock material and the size and shape of the crack.   3. Hoek...
