One of the ways longwall mines achieve or exceed their owners’ expectations is through the use of highly efficient Longwall Top Coal Caving (LTCC) technology production, in combination with the extensive use of automation. LTCC remains a seldom used method for mining high seams efficiently and ecologically with sustainable use of deposits.
Longwall Top Coal Caving (LTCC) technology LTCC allows the excavation of thick coal seams of 5 to 12 metres at one pass of the longwall machine, generating high productivity and economic returns for
Longwall Top Coal Caving (LTCC) is a special designed longwall mining method for very thick seams (thickness is more than 4.5m) where good quality coal is being left because "conventional" longwall equipment has not yet been designed to operate successfully beyond around 5m mining height.
Longwall Top-Coal Caving isn’t just an alternative mining technique; it can be the difference between a productive, profitable mine and an unsustainable operation. The technology reduces waste and operating costs, making for a more efficient operation.
New era hinges on Austar. A lot hinges on DBT’s success at introducing longwall top coal caving (LTCC) to Yanzhou Coal’s Austar mine. Simply put, Austar and
That is why longwall owners have high performance expectations, especially in tough economic times when commodity prices are low. Read a whitepaper highlighting one of the ways longwall mines achieve or exceed expectations, through the use of highly efficient Longwall Top Coal Caving (LTCC) technology production, in combination with the
2Zhangji Coal Mine, Xuzhou Mining Bureau, Xuzhou 221147, Jiangsu Province, P.R of China ABSTRACT Longwall top-coal caving technology has developed rapidly in China, in recent years. The application of longwall top-coal caving can double both the productivity and the efficiency of a working face and reduce the cost of production by 30 to 40o/o.
Longwall Top Coal Caving has been considered as one of the most effective technologies for the extraction of underground thick coal seams. A large number of studies on the applicability of Longwall Top Coal Caving into new mine sites have linked the success of its application to the geomechanical understanding of the cavability of the top coal.
Longwall Top Coal Caving (LTCC) technology. LTCC allows the excavation of thick coal seams of 5 to 12 metres at one pass of the longwall machine, generating high productivity and economic returns for an operation. Ultra Clean Coal (UCC) technology.
On top of this, if there are present dams near to the longwall mining site, this could doubly impact the riparian ecosystems as it would have a reduced inflow rate as well as the loss to the underlying rock fracturing. As of 2014, measures were taken by the Australian government to mitigate water impacts from longwall mining.

This paper presents a new criterion for assessing top coal cavability in Longwall Top Coal Caving mining technology. Top coal Cavability Index (TCI) criterion was developed through a parametric study, statistical analysis and validation against field monitoring data.
Longwall top-coal caving technology has developed rapidly in China, in recent years. The application of longwall top-coal caving can double both the productivity and the efficiency of a working face and reduce the cost of production by 30 to 50%.
Longwall top coal caving (LTCC) The paper discusses advanced top coal caving technologies for thick coal seams and addresses some issues of incomplete coal extraction, which can result in the environmental damage, landscape change, air and water pollution and endogenous fires.
On top of this, if there are present dams near to the longwall mining site, this could doubly impact the riparian ecosystems as it would have a reduced inflow rate as well as the loss to the underlying rock fracturing. As of 2014, measures were taken by the Australian government to mitigate water impacts from longwall mining.
The main objective of the project is to develop design tools and technology to facilitate the application of the LTCC method in Australia. The project has developed a geotechnical top coal caving model and assessment procedure, an understanding of the environmental hazards and an optimum top coal
