A Review on Mining Induced Earthquake
Abstract: Seismicity in mines, in general, depends on depth, production rate, mining geometry and geological discontinuities such as dykes, faults etc. Induced earthquakes differ from normal earthquakes in that they have occurred prematurely due to an external trigger. Except for much of the micro seismicity, the virgin state of stress in the Earth’s crust depends on, among other factors, gravity and tectonics. In, or near, a mine the stress state is …

Fuel Less Slingshot Rocket to Flies a Certain Distance Using Costless and Ecofriendly Fuel
Abstract: In this study, the rocket travels a certain distance by utilizing the force provided by the alternative of using potassium nitrate (KNO3) and sugar (C12H22O11). this initial burst reduces the amount of fuel needed for the rocket to achive the necessary speeds and altitudes. Slingshot physics involves using stored elastic energy to shoot something at high speed. This energy comes from specially made elastic bands for slingshots and is initially …
