Determining the strength of coke under crushing forces ...

Abstract. The method used to determine the coke's ability to withstand abrasive and impact forces has been codified in GOST State Standards (in terms of the strength indices M 25, M 40, and M 10 ). However, there is no standard method for assessing the ability of the coke to withstand crushing forces.

What is Prototype model advantages, disadvantages and ...

The basic idea in Prototype model is that instead of freezing the requirements before a design or coding can proceed, a throwaway prototype is built to understand the requirements. This prototype is developed based on the currently known requirements. Prototype model is a software development using this prototype, the client can get an "actual feel" of the system, since the ...

Determining the strength of coke under crushing forces ...

To address that deficiency, a compact system for determination of the coke's ability to withstand crushing forces is proposed: it consists of a press for the creation of compressive forces; a matrix with a punch in which the coke sample may be placed; and an instrument for measuring the compressive force (the crushing force).

Effect of Mining Thickness on Overburden Movement and ...

Because the coal seam is particularly thick and the mining intensity is large, the mining of extremely thick coal seams often causes a wide range of disturbed fractures, which in turn induces the phenomenon of strong underground pressure such as induced support crushing and water inrush. Through theoretical analysis, laboratory similarity simulation test, and other methods, this paper studies ...
