MODEL OF FISSURED ROCK MASS EXPOSED BY BORE-HOLE

摘要

FIELD: mining industry. SUBSTANCE: model can be used in laboratory investigations of process of cementation of fissured rock matter. Model of fissured rock mass comprises bore-hole and structural component which simulates fissured rock matter. Structural component is made in the form of filtration chamber which is divided in length into spaces by partitions. Located in upper part of spaces are throttles. Resistance of throttles is assumed as being equal to resistance of fissures to flow of cement slurry through them in simulated section of bore-hole. Volume of filtration chamber is taken as equal to volume of fissures in simulated volume of rock matter. Distribution of volumes of spaces in chamber is taken as being similar to distribution of fissure hollowness in rock matter proportional to distance away from bore-hole. Aforesaid model allows for simulating process of injecting cement slurries into fissured rock matter through bore-holes. EFFECT: higher efficiency. 1 cl, 1 dwg
