Combined Mining

The Combined Group

Combined Mining Services attended the Men's Physical and Mental Health Luncheon at the Sage Hotel Wollongong, hosted by ARHG Foundation. The Luncheon was to promote excellence in men's physical and mental health, for men to learn about their health, and make positive changes in their lives. Tim Atherton, Director of TCG and Australian ...

Combined prediction model for mining subsidence in coal mining …

The entire overburden stratum above a coal mining area is considered to be composed of an alluvial soil layer and a bedrock layer. In underground mining, alluvial soil has a major effect on ground subsidence. This effect is especially significant and not negligible when the alluvial soil accounts for a large proportion in the entire overlying stratum of coal mining …

The accurate prediction of the height of the water-conducting fracture zone is essential for the prevention of roof damage by water disasters in coal mines. The development law of water-conducting fracture zone in combined mining of Jurassic and Carboniferous coal seams is different from that of previous research results. This study constructed an …

Combined mining: Analyzing object and pattern relations …

Combined mining is a technique for analyzing object relations and pattern relations, and for extracting and constructing actionable knowledge (patterns or exceptions). Although combined patterns can be built within a single method, such as combined sequential patterns by aggregating relevant frequent sequences, this knowledge is composed of ...

Combined Text-Mining/DEA method for measuring level of …

The case study showed that the proposed text-mining/DEA combination method can be effectively utilized to determine LCS from online reviews. Above all, the proposed approach provided for a multi-service dimension-based LCS evaluation, showing that more sophisticated evaluation and analysis than the service rating score provided by many …

A New Combined Mining Method: The Stope Limit Length …

To tackle the technical challenges of medium-depth mining in sharply inclined medium-thickness ore bodies, the concept of an induced caving crown pillar was introduced, which led to the development of temporary crown pillar-induced caving technology. Building upon this foundation, a combined mining method of crown-pillar induced caving and non …

Stability analysis of PSHP affected by the CUOPM

The construction of a pumped storage hydropower plant (PSHP) in an abandoned open-pit mine is a potential alternative to green mining and energy storage, which can increase the utilization rate of renewable energy and develop residual resources of abandoned mines. Dynamic surface subsidence affected by combined underground and open-pit mining …
