Hrebeniuk T. Block stone winning static dynamic method process-dependent parameters proof

The dissertation is dedicated to the block stone winning static dynamic method process-dependent parameters proof and improvement. Borehole line crack initiation process with static loading is investigated and process-dependent parameters calculations analytic formula for pressure and borehole distance depending on their radius and mineral characteristics is gained for plane perfect plasticity problem. Processing equipment for diffraction resonant type mode for qualitative block stone flushing with balanced borehole tension possible establishment is theoretically proved. Original strategy for experimental investigation of static and dynamic stress field interaction, while stone block winning with static dynamic borehole method, is developed. Uncovered pulse tailing effect shows more rational cracks initiation with dynamic loading, while static loaded boreholes create favorable conditions for their steady spreading with significant borehole distance increase. Developed pressure units application made it possible to generate lower power inputs monolith flushing directed line and avoid destruction in flushing line zone. Granite controlled flushing developed system implementation certificates confirm advantages over other technologies in possibility of static loading predictable conditions while ecologically safe process.
