Stability of underground excavations is of great importance to an operating mine because it ensures the safety of working people and operating facilities as well as successful ore production. The rock mass stability around underground excavations heavily depends on the mechanical behavior of intact rock and discontinuities, the discontinuity geometry pattern and the in-situ stress system.

Te process of assessing a rock slope for stability involves the application of many branches of engineering and natural science. Te determination of rock or soil strength parameters requires a working knowledge of rock mechanics and/or soil mechanics. Knowledge of basic hydrological concepts is essential for interpreting the efects of water on a rock slope. An understanding of geology—especially structural geology, mineralogy, petrology, and the geological processes—is extremely important for the rock slope engineer. Tese areas of knowledge—geology, rock and soil mechanics, and hydrology—along with other basic areas such as statics, engineering mechanics, statistics, and structural engineering are all important elements of rock slope engineering and design. <...>

Рассматриваются научные аспекты изучения деформационных процессов и напряженного состояния толщи горных пород в районах широкомасштабного освоения недр с учетом наличия систем тектонических разломов и разрывных нарушений разного уровня, а также основы создания комплексных систем геодинамического мониторинга за поведением, устойчивостью и состоянием таких регионов.

Design of slope angles for open pit slopes have become increasingly important as mining depths in open pits worldwide continue to increase. Even a minor decrease of the slope angle leads to large additional costs due to increased waste rock extraction. On the other hand, with increased slope angles comes an increased risk of slope failure. A large scale failure can be very disastrous both to the operation and to the personnel working in the mine. <...>

Модели прочности на сдвиг в двухмерном и трехмерном измерениях для оценки устойчивости анизотропных горных склонов в регионе Пилбара в Западной Австралии.

The bedded iron ore and gold deposits in the Pilbara Region of Western Australia are hosted in highly anisotropic rock masses. For iron ore, these comprise strong banded iron formations discretely interbedded with very weak shales. Gold and other precious metals deposits in the same region are hosted by interbedded siltstones, sandstone and quartzites. Slope instability mechanisms generally involve sliding along bedding planes combined with joints or faults acting as release planes.
