TLDR
In this paper, the authors investigated the cuttability of evaporites and reported the results of a large-scale experimental work carried out in the Mining Engineering Department of the University of Newcastle upon Tyne.Abstract:
With ever-rising labour costs, the mining engineer and the underground civil engineer look to mechanical excavation systems to increase productivity. The research described in this paper was part of a major and long term programme of experimental work carried out in the Mining Engineering Department of the University of Newcastle upon Tyne. One of the objectives of this research was to investigate the cuttability of evaporites. To this end each rock which has been tested for its cutting properties has also been subjected to a wide range of physical and mechanical tests. All the results are discussed in this paper.read more

Estimation of rock modulus: For intact rocks with an artificial neural network and for rock masses with a new empirical equation
TL;DR: In this article, the elastic modulus of intact rock is used for many rock engineering projects, such as tunnels, slopes, and foundations, but due to the requirements of high-quality core samples and associated sophisticated test equipment, instead the use of empirical models to obtain this parameter has been an attractive research topic.

Specific energy as a criterion for the use of rapid excavation systems in Turkish mines
TL;DR: In this article, it is shown that mechanization of mines by means of roadheaders, continuous miners, impact hammers and tunnel-boring machines allows continuous operation and it is, therefore, to be expected that mechanisation of mines can be achieved by using roadheaders and continuous miners.

Brittleness and micro-scale rock cutting efficiency
TL;DR: In this article, a more common formulation of brittleness, from compressive and tensile strength, has been adopted to evaluate the relationship between the two parameters and the cutting efficiency of chisel picks.
Petrographic Record and Conditions of Expansive Hydration of Anhydrite in the Recent Weathering Zone at the Abandoned Dingwall Gypsum Quarry, Nova Scotia, Canada
TL;DR: In the Dingwall gypsum quarry in Nova Scotia, Canada, operating in 1933-1955, it was recognized that gypsi-cation commonly starts from a developing network of tiny fractures penetrating massive anhydrite as discussed by the authors .

Application of Bayesian approach in geotechnical engineering
TL;DR: In this article, a set of Bayesian methods for estimating the modulo de deformación of a macizo rocoso are presented, with an emphasis on the uncertainty of the predictions.
