  • Preliminary Analysis of Quarry Slopes in a Weathered Rock

    This chapter presents a preliminary analysis of quarry slopes in a weathered rock mass profile The problem of evaluating the stability of slopes in jgeneral, each bedding plane marks the termination of one deposit and the beginning of another DEFINITION OF MAJOR GEOLOGIC FEATURES IN THESE ROCK TYPES OBSERVED TO INFLUENCE EXPLOSIVE BLASTING The following major geologic features were observed to affect explosive blasting in limestone and dolomite quarriesDesigning Blast Patterns Using Empirical FormulasThis type of weathering creates new minerals in place of the ones it destroys in the parent rockAs rocks are exposed to atmospheric conditions at or near the ground surface, they react withcomponents of the atmosphere to form new minerals The most important atmospheric reactantsare oxygen, carbon dioxide, and water In polluted air, other reactants are available (acid rainproblemsPHYSICAL PROPERTIES OF ROCK

  • Evaluation of ground vibration effect of blasting

    In order to achieve a reasonable fly rock distance for providing safety in mines, decrease in the fly rock is one of the main worries of the blasting designers [20,21,22,23,24,25,26,27,28,29,30]Sri Lankan practices for quarry operation and challenges in the quarry industry to in operation the quarries as discussed in the Chapter 3 32 Explosives Several kinds of explosive material are used for rock blasting The materials mainly used for quarry blasting in Sri Lanka are, 1 ANFO(Ammonium Nitrate and Fuel Oil) 2 Dynamite 3 Water gelCHAPTER 3 QUARRY BLASTING PRACTICES IN SRI LANKAAccording to previous scientists, up to 8085% of the energy of explosives was wasted and produced ill effects, such as ground vibration (PPV), air overpressure, fly rock, dust and toxic [4][5][6Analysis of parameters of ground vibration produced from

    Such waste rock or refuse has to be dumped on one or other side of the quarry, so that main quarry face is not blocked The required dumping space should be easily available near the quarry (v) Another factor is drainage system: Ground waterGeneral conclusions for this transport system The rolling stone carrier was a simple design and made of local available materials This tool made it possible to transport heavy stone blocks in an efficient way and with human power The carrierThe Great Pyramid and Transport of Heavy Stone BlocksExplosive energy is used to break rock However, the use of this energy is not 100percent efficient Some of the energy escapes into the atmosphere to generate airblast or air vibrations Some of the energy also leaves the blast site through the surface soil and bedrock in the form of Controlling the Adverse Effects of Blasting
