Abstract:
Methods and systems are described for efficiently operating haulers of varying sizes for transporting mined material at a mine site. The haulers can include "right-sized haul trucks (RSATs)". Methods and systems are also described for efficiently using containers for mined material, including loading, handling and transporting mined material within a mine or from a mine. The containers can be carried on haulers such as "movable units" and "moving units".
Abstract:
A hydraulic fracturing equipment installation located above-ground drills a plurality of holes downwardly into the rock mass and injects a hydraulic fracturing fluid into the drilled holes and induces fractures in the rock mass. A non-metallic casing for drilled holes is also disclosed.
Abstract:
본 발명은 따른 채석용 갱도 구조체 및 이를 이용한 채석 방법에 관한 것으로 석산의 내부에 기울어지게 위치되어 상기 석산의 상부에 위치되는 채취 장소에서 채취된 석재가 내부에서 굴러 자유낙하되어 지상으로 낙하시키는 석재 이송용 갱도부를 포함하여 석산에서 채석되는 석재를 석산의 내부에 경사지게 위치되는 갱도를 통해 지상으로 자연 낙하시킴으로써 석산에서 채취된 석재를 지상으로 이송시키는데 소요되는 비용과 시간을 크게 절감하여 석재의 채취 효율을 향상시키고, 석재의 이송 효율을 크게 향상시키며, 석산에서 채취된 석재를 지상으로 이송시키는데 발생되는 소음이나 진동, 분진 등의 공해 피해를 최소화하여 석산의 주변에 거주하는 주민과의 마찰을 최소화하고, 주민의 피해를 최소화할 수 있다.
Abstract:
According to an example aspect of the present invention, there is provided a method, comprising: (310) receiving a tunnel model of an underground tunnel system of a worksite, (320) receiving a route point entry indicative of a route point position for a mine vehicle in the tunnel system, (330) defining, for controlling obstacle detection for the mine vehicle, at least one lateral safety margin parameter on the basis of vehicle dimension data and processing the tunnel model in respect to the route point position, and (340) associating the at least one lateral safety margin parameter with the route point position.
Abstract:
The present invention provides a method and an apparatus for creating a void, low-density fill or combination of void and low-density fill for underground mining comprising at least one module of formwork to be positioned in an open stope of an underground mine prior to carrying out a backfilling operation.
