Stability analyses of submicron-boron mineral prepared by mechanical milling process in concrete roads
(Elsevier Sci Ltd, 2016)
The main objective of this study is to investigate the possibility of utilizing nano/submicron sized boron mineral (colemanite) in Portland cement concrete. Colemanite was obtained from a mine in three different sizes as ...
A solution to the time-dependent stress sistribution in suborbicular backfilled stope interaction with creeping rock
(Hindawi, 2021)
The creep behavior of deep weak rock masses is important due to an underground opening. Appreciating the nature and source of these deformations requires the knowledge of rock mass and ground support interaction. The ...
CT scanning of internal crack mechanism and strength behavior of cement-fiber-tailings matrix composites
(Elsevier Ltd, 2021)
This paper deals the relationship between compressive strength and internal crack formation (e.g., crack width and volume) of cement-fiber-tailings matrix composites (CFTMC) using an industrial computed tomography system ...
Analysis of strength and microstructural characteristics of mine backfills containing fly ash and desulfurized gypsum
(MDPI, 2021)
The utilization of solid wastes (SWs) as a potential resource for backfilling is not only conducive to environmental protection but also reduces the surface storage of waste. Two types of SWs, including fly ash (FA) and ...
The durability of high-strength concrete containing waste tire steel fiber and Ccal fly ash
(Hindawi, 2021)
The demands for high-strength concrete (HSC) have been increasing rapidly in the construction industry due to the requirements of thin and durable structural elements. HSC is highly brittle. Therefore, to augment its ...
Stability investigation of a deep shaft using different methods
(ASCE- American Society of Civil Engineers, 2021)
The New Zigana Tunnel is, at 14.5 km long, the longest highway tunnel project in Turkey. In this project, it is planned to construct two service shafts to provide access to outside the tunnel and temporary ventilation. ...
Investigation of continuous and discontinuous contact cases in the contact mechanics of graded materials using analytical method and FEM
(Techno-Press, 2021)
The aim of this paper was to examine the continuous and discontinuous contact problems between the functionally graded (FG) layer pressed with a uniformly distributed load and homogeneous half plane using an analytical ...
Analyzing the contact problem of a functionally graded layer resting on an elastic half plane with theory of elasticity, finite element method and multilayer perceptron
(Techno-Press, 2021)
This paper presents a comparative study of analytical method, finite element method (FEM) and Multilayer Perceptron (MLP) for analysis of a contact problem. The problem consists of a functionally graded (FG) layer resting ...
Additivity effect on properties of cemented coal fly ash backfill containing water-reducing admixtures
(Elsevier Ltd, 2021)
Cemented coal fly ash backfill (CCB), a flowable structure of coal fly ash, binding agent and mixing water, has been often employed in mining operations to offer ground support as well as waste disposal solutions. An ...
Analysis of tensile mechanical characteristics of fibre reinforced backfill through splitting tensile and three-point bending tests
(Taylor & Francis Ltd., 2021)
The cut-and-fill mining method is used in metalliferous mines thanks to backfilling instead of ore pillars. However, the stability of the artificial cemented tailings backfill (CTB) roof is one of the key influencing factors ...
