Experimental determination of the boundaries of the influence of a stope working on the earth's surface

The theoretical part of the research methodology is developed according to scheme subsidence points on earth's surface relative projection face. curve trajectory divided by characteristic at different stages surface. Such include: beginning displacement surface, active stage displacement, end and attenuation processes According goal design scheme, basis experimental data, we determined parameters corresponding location a point where it began settle. In relation under consideration, three well-known dependencies were analyzed describe surface: exponential equation, hyperbolic tangent function, logistic curve. Based them, was established that main influencing factor determining boundary dynamic half-mold depth mining operations, angles are practically independent this parameter.
