Coal Exploration and Mining Geology
2020-8-18 begins operation. Coal mining geology embraces a number of special skills and techniques, but is otherwise essentially a continuation of exploration activities into the production phase of the project. 2. Objectives of Coal Exploration Programs As indicated above, coal exploration is the first part of a continuous process, that if

A mathematical hydraulic support self-tracking model for three-machine cooperative mining is proposed to address low efficiency and difficulties in strategy evaluation of a fully mechanized coal face. The proposed model uses the coordinates and traction speed of the shearer to calculate the frequency of the circular hydraulic support and realize the coordinated operation of the three-machine ...

Optimisation of operating variables of fine coal flotation ...
2003-1-1 The actual values of R ∞ (obtained at the “flotation time”) and k s obtained in the lab tests were used to draw the time recovery curves for combustibles and ash. Fig. 1 shows a typical time recovery curve for combustibles and Fig. 2 shows a plot of ln(1−(R/R ∞)) vs. time t.The figures clearly show that the flotation tests follow a first-order rate equation.

Abstract Optimisation of flotation parameters using rate models is not a new concept. The kinetic model based on time recovery data, which uses the extra dimension of rate, has been in vogue since time immemorial for scaling up of lab data. Often, interpretation on the performance of a flotation circuit, based only on R ∞ (the ultimate recovery) and k s (the first-order rate constant of the ...
