A method of drilling vertical and horizontal pathways to mine for solid natural resources involves a drill bit, at least one reamer, a first plugging material, and a second plugging material; drilling a testing wellbore to a specific vertical depth with the drill bit and identifying at least one desired mining section wherein the desired mining section is associated with a corresponding vertical depth; creating a new bottom end for the testing wellbore by filling the testing wellbore up to an offset distance with the first plugging material; drilling a horizontal access hole from the new bottom end into the desired mining section with the drill bit and enlarging it with a reamer; excavating cuttings from the desired mining section through the horizontal access hole; filling the horizontal access hole with the second plugging material; and repeating the drilling, enlarging, and filling process to create a plurality of lateral holes.

Method of moving material

The invention is directed to a method of strip mining that involves dividing the pit into blocks in a diamond shape arrangement with an angular advancing strike face and removing waste material from each diagonally adjacent block so as to minimize the amount of waste material pushed by dozers and maintain the incline of ramps to gradients of 10% or less so that trucks can take mined ore from the pit.

Mining method and use of mined material in production of graphene and graphitic material
10676834 · 2020-06-09 · ·

A mining method (10) by which graphitic ore is produced in a form that constitutes an appropriate feedstock for an electrolytic process (20) for the production of graphitic materials through exfoliation. The graphitic ore feedstock may be utilised directly as an electrode in the electrolytic process (20). Also disclosed is a graphitic feedstock for an electrolytic process for the production of graphitic material through exfoliation of that feedstock, wherein the feedstock is less than about 99% graphite (w/w) and of a sufficiently cohesive and conductive nature as to allow electrochemical exfoliation therethroughout without fracturing that might result in collapse of a significant portion of the feedstock or that may result in a loss of conductivity throughout a significant portion of the feedstock.
