WebSep 30, 2024 · In short, the partial backfill mining technique is, at present, only applied with success to exploit near-horizontal and gently inclined coal seams, whereas its application to steep coal seams to control surface subsidence and water conservation has not progressed beyond the experimental stage. WebFeb 21, 2007 · If a wall is prevented from even slight movement, then the earth remains at or near the value of at-rest conditions. The coefficient of earth pressure at-rest, Ko, for normally consolidated cohesive or granular soils is approximately: Ko, = 1-sin [theta]'. where: [theta]' = effective friction angle. Thus for [theta]' = 30 degrees, Ko, = 0.5.

An analytical approach is then proposed to compute the static passive and active … WebApr 4, 2024 · Using Rankine’s approach for a granular backfill, and assuming that the pressure acts in a vertical backface, the passive earth-pressure coefficient may be calculated using the expressions: When the backfill is completely horizontal º K p = t a n 2 ( 45 º + ϕ ′ 2) When the backfill is inclined a certain angle with respect to the horizontal
WebIn this paper, a theoretical model is presented and applied to obtain and calculate the lateral pressures exerted on the filling barricade and to understand the effects of the filling process. It is found that the yield stress of cemented backfill increases with curing time and this relationship can be described as an increasing power function.
