The invention relates to a structured light quick scanning microscopic imaging method. The method comprises the following steps of: (1) controlling a spatial light modulator to generate a modulation pattern with single spatial frequency by a computer, and projecting the modulation pattern on a sample fracture; (2) under the condition that the phase of the modulation pattern is unchanged, driving a sample to move by an electric control movement platform, and synchronously triggering a line-scan digital camera to take a picture; (3) changing the phase of the modulation pattern, and scanning the same imaging region until different lighting phase images required by structured light imaging is acquired; and (4) moving a sample, and executing the steps (2) to (4) for the subsequent adjacent imaging region until the whole sample fracture is scanned.

A method for extracting mineral deposits in a mineral reserve, a portion being accessible from a sloping surface and the remaining portion being inaccessible, is disclosed. The sloping surface is mined to create a bench and highwall for providing access to the mineral reserve around the accessible portion. Then, a surface is formed in the highwall to create an insertion highwall between an endwall extending from the insertion highwall and the inaccessible portion of the mineral reserve. A starter entry is created for cutting into the mineral reserve across the entire length of the insertion highwall from the endwall to the inaccessible portion of the mineral reserve. Roof supports are advanced into the starter entry with spoil added to form a starter passage from the endwall to the inaccessible portion of the mineral reserve. Shortwall or longwall mining techniques are then used to mine the mineral reserve along the starter passage. Canopies are positioned at both ends of the starter passage to seal the passage and provide ventilation of the active mining area by the introduction of air along the face of the mineral seam. A single-gate passage is formed extending from the insertion highwall adjacent the inaccessible portion of the mineral reserve to allow the continuous miner to form another opposing endwall. Mining then continues in the starter passage along the insertion highwall from the single-gate passage to the opposing endwall, thereby forming a production passage into which the roof supports are farther advanced with gob forming behind.
