摘要： The present disclosure relates to a technical field of coal mining, particularly to a method of no-pillar mining with gob-entry retaining adapted for fully-mechanized top coal caving in a thick coal seam, which comprises the following steps: reinforcing support on a roof and two sides of a roadway; performing roof slitting blasting to form a pre-splitting slit; erecting a temporary support device and a gangue retaining device in the roadway along the retained entry; performing no caving within a range of a preset distance at an end of the working face near the retained entry side; and removing the temporary support device in the roadway after entry forming stabilizes, and closing the goaf to complete entry retaining. The roof slitting blasting is more beneficial to collapse of strata in the goaf, so that the strata in the slit can better fill stoping space after collapse, and the roof of the retained entry forms a short arm beam structure laterally, which avoids forming a long suspended roof in the goaf, and improves the stress of surrounding rock of gob-side entry retaining; coal caving is not performed in a certain range at the end of the working face of the retained entry side, which further ensures the filling effect of the goaf on the retained entry side, effectively limits the rotary sinking of blocks of the main roof, and greatly reduces effect on the stability of the retained entry.

摘要： Disclosed is a drill and blast method for advancing the tunnel face in a mine, which makes use of a mobile canopy. The mobile canopy having vertical supports connected to a frame that supports a shield. The mobile canopy allows for face production activities and ground support activities to occur simultaneously or near simultaneously. This allows for more rapid advancement of the tunnel face compared to traditional batch drill and blast techniques.

摘要： In combination a loader unit and haul unit for use in a block caving mining operation. Each of the loader unit and the haul unit comprise a removable bucket, which can be used for loading ore. In use the bucket carrying a load of ore can be transferred from the loader unit to the haul unit so that the haul unit can transport the ore from a loading site to a crusher. The loader unit and haul unit have a respective longitudinal axis extending from the fore end to the aft thereof, and the bucket is elongate with a longitudinal axis. In use when the bucket is mounted to the loader unit the longitudinal axis of the bucket is disposed orthogonally to the longitudinal axis of the loader unit. When the bucket is transferred to the haul unit, the bucket is placed upright on the haul unit with the longitudinal axis of the bucket parallel to the longitudinal axis of the haul unit.

摘要： A method for in situ solution mining of a mineral from an underground evaporite stratum using a set of wells in fluid communication with at least one mineral cavity with some wells operated in solvent injection mode and other wells operated in brine production mode and optionally with some inactive wells, comprising switching the operation mode of one or more wells. The evaporite mineral preferably comprises trona. The at least one cavity is preferably formed by lithological displacement of the evaporite stratum at a weak interface with an underlying insoluble stratum by application of a lifting hydraulic pressure. The extracted brine can be processed to make valuable products such as soda ash and/or any derivatives thereof, rock salt, or potash. This method can provide more uniform dissolution of mineral in the cavity, can minimize flow channeling, can minimize sodium bicarbonate blinding for solution mining of incongruent trona ore, and/or may avoid uneven deposit of insolubles.

摘要： A method of mining a mineral deposit includes setting a plurality of explosive charges at spaced pre-blast locations in the deposit, wherein at least selected pre-blast locations also carry respective markers that are such that the post-blast location of at least a useful proportion will be detectable after explosion of the charges. After the charges are exploded to fragment the deposit, the post-blast locations of certain of the markers are detected to obtain an indication of the relative positions of selected components of the mineral deposit after the fragmentation of the deposit by the exploding of the charges. Also disclosed is a method utilising a plurality of markers arranged to emit a detectable signal after blast fragmentation, and detecting the post-blast locations by triangulation techniques employing a plurality of receiver detectors. A further aspect proposes the use of secondary explosive charges as post-blast markers.
