In order to study the factors that affect the failure depth of coal seam floors such as mining depth, coal seam pitch, mining thickness, workface length and faults, we propose a combined artificial neural networks (ANN) prediction model for failure depth of coal seam floors on the basis of existing engineering data by using genetic algorithms to train the ANN.
To make a video game of Mega-Super-Soccer (for example) they might add many elements like super-kicks and powerups, bringing more elements onto the pitch (mines, laser beams), changing the scoring conditions away from simple trading maybe to something more exotic like having multiple kinds of goal, or two balls.
His virtuosic pitch — like mine — begins with a theatrical and rather bizarre statement.
"The low pitch is mine, but once it gets upstairs, I can't hit it".
It utilizes characteristics of the coal seam/s and associated underlying and overlying strata (geologic, hydro-geologic, and geometric such as seam pitch, anomalies), mining operations (panel width, panel length, mining rate, etc)., regional subsidence characteristics (angle of draw, angle of break, tensile and compressive strain, etc)., and surface topography to achieve this.
"Those huge doors come down and you're in a pitch-black mine," Lean said.
There's always something satisfying when characters on TV escape their goldfish memories and refer to things that have happened in the show's past – and hearing Larry pitch incidents mined from the last six years of Curb to the Seinfeld cast as possible storylines for their characters is a great touch.
Instead of hell, purgatory and heaven, Zhao's camera plunges through pitch-black mines, hellfire iron furnaces and a gleaming ghost city.
