摘要： Provided is a method of forming a roadway by filling gangue paste during wide roadway excavation of a thick coal seam belonging to the technical field of mining industry. The method comprises: firstly designing a width of a filing strip and a width of a new excavation roadway according to a geological condition of a coal seam; secondly, determining a length of each filling, i.e. a cyclic filling interval, according to an existing excavation technical condition of a mining shaft; when the new excavation roadway is excavated, performing supporting for a roof, a floor and an inner side of a roadway by using a strong bolt and bolt-mesh-cable; then, after the new excavation roadway is excavated for the cyclic filling interval, starting to perform roadway-expanding excavation along an outer side of the roadway; when roadway-expanding excavation is performed, performing temporary supporting for a filling strip and a junction of the filling strip and the new excavation roadway by using a single hydraulic prop in cooperation with a metal articulated roof beam; finally, after roadway-expanding excavation is completed, removing temporary supports and filling the filling strip; afterwards, the above steps are performed alternately. In this way, coal losses caused by reserving coal pillars can be effectively reduced, the impact of the underground pressure during roadway excavation is relieved and the costs of gangue treatment and roadway excavation are lowered.

摘要： A method of disposal or temporary storage of fine particulate solid waste material or a mixture of such solid material with liquid including pumping the solid material entrained in liquid through a pipeline by means of a piston pump into a natural or artificial dump space above ground or below ground. To pump fine grained waste materials, for example dusty or paste-like and sludge-like waste materials, without incurring problems regarding the entrainment liquid and to prevent, in the case of underground storage, the production of a geologically insufficiently stable packing in a natural or artificial cavity, a high-consistency mixture containing less than 20% by weight of liquid, which is generally water, is pumped into the space by means of the piston pump.

摘要： A method of this disclosure directionally drills at least one well extending from ground surface to an interior of an underground mine located below ground, the well being at an oblique angle relative to vertical; blends or mixes together a hazardous material, like lead, zinc, arsenic, and cadmium with cement including a plasticizer; pumps or flows the mixture into the well, wherein the mixture flows toward a lower end of the mine and hardens in place. The method allows for the permanent placement of contaminated mixtures like chat into mines or shafts or depositories, as defined by the United States Environmental Protection Agency, CERCLA and Superfund laws and complies with rules for the permanent closing of these structures with contaminated material and contaminated substances.

摘要： A plug for a void in a mine to divert water having a rigid closed cell foam which fills the void. The rigid closed cell foam having a plurality of pipes disposed within the foam. The pipes distributed throughout the void. The pipes are positioned in the foam so the pipes are staggered in length vertically with respect to various heights in the void, and the pipes are positioned in the foam every 4′ to 6′ horizontally with respect to the void. Each pipe has a mixing stick. A method for diverting water from a void in a mine.

摘要： Provided is a filling mining method for a fully-mechanized top coal caving working face, which relates to the field of mining engineering technologies. The method solves the technical problems of roof control of the fully-mechanized top coal caving working face and a large ground deformation of top coal caving mining. The method includes the following steps: at step A, dividing the fully-mechanized top coal caving working face into a filling zone and a top coal caving zone along a strike of the working face, or dividing the working face into a filling zone and a top coal caving zone along a strike and an inclination of the working face; at step B, determining a cycle interval of the working face; at step C, performing supporting for the filling zone before the working face, and completing coal caving in the top coal caving zone and performing round wood supporting in the filling zone; at step D, after the filling zone reaches the filling interval, disposing a filling tarpaulin behind a hydraulic support and pumping the filling paste; at step E, repeating steps C and D to complete mining. A mining method of alternate coal caving and filling is provided to complete the filling mining of the top coal caving working face. In this way, the roof is effectively controlled, ground subsidence is reduced and advantages such as safety and high efficiency are available.
