  • Patent number: 10895152
    Abstract: Breaking rock and concrete, based upon a Controlled-Foam Injection or PCF (Penetrating Cone Fracture) uses a high-pressure fluid to pressurize a pre-drilled hole. A high pressure seal is formed between the injection barrel and walls of the pre-drilled hole in the material to be broken. A leak-free poppet valve holds a fluid in a pressure vessel before rapid discharge. Variable charges of foam/water are generated and delivered to the breaker. The injection barrel is prefilled with a low viscosity fluid. An annular reverse acting poppet valve allows concurrent injection of chemical additives and/or micro particles to modify foam viscosity during its high pressure release into the material to be broken. A high pressure foam generator is compact and reliable. Removal and wash-out of the seal frees the injection barrel.

  • Patent number: 10895153
    Abstract: A vibrating type hard rock cutting mechanism with a function of directional high-speed abrasive jet advanced slitting includes a disc-shaped hob, a cutting main shaft and a valve plate. When the vibrating type hard rock cutting mechanism works, an outlet of a high-pressure abrasive jet generating system is communicated to a cutting mechanism abrasive jet inlet. An abrasive jet enters an abrasive jet nozzle through flow channels in the valve plate, the cutting main shaft and the disc-shaped hob and forms a directional high-speed abrasive jet. The cutting main shaft is directly driven to rotate by an axial permanent magnet motor. The cutting mechanism enables the disc-shaped hob to vibrate under the action of a vibration motor. A macro crack is formed on a rock mass by rotating the abrasive jet. The rotating disc-shaped hob can be wedged into the formed crack in a vibration manner by swinging the cutting mechanism.

  • Patent number: 10882086
    Abstract: Described herein are embodiments of a control system that automatically (1) determines whether a gas extraction system is in a state in which landfill gas is being released into the atmosphere, and (2) automatically controls landfill gas flow to mitigate, prevent and/or stop the release of landfill gas. The control system may control a valve to control flow of landfill gas through well piping of the gas extraction system. The pressure of landfill gas in the well piping at a location upstream of the valve may indicate whether there is a risk of landfill gas being released into the atmosphere. The control system may adjust a position of the valve in response to determining that the pressure at the location upstream of the valve indicates that there is a risk of landfill gas being released into the atmosphere.

  • Patent number: 10876403
    Abstract: A method for mining an ultra-thick coal seam by utilizing a goaf solid backfilling technique is suitable for mining an ultra-thick coal seam having a thickness of 25 m-45 m. According to the method, the ultra-thick coal seam is sliced into three slices, i.e. an upper slice, a middle slice and a lower slice. First, the middle slice is subjected to solid backfilling and mining. Metal meshes are paved along a working face of the floor. The backfilling layer serves as an artificial floor for mining the upper slice and an artificial roof for mining the lower slice. Then, the upper slice is mined by the top coal caving mining based on the artificial floor formed by backfilling the goaf of the middle slice. Finally, the lower slice is mined by the top coal caving mining along the coal seam floor with the shield of the artificial roof.

  • Patent number: 10851627
    Abstract: A system for extracting landfill gas from a landfill is provided. According to some embodiments, a control system for landfill gas extraction is provided. The control system uses a throttle to control flow of landfill gas extracted from the landfill. The throttle is actuated in use to vary the flow of gas between a well and a gas collection system, in accordance with a control algorithm that adjusts flow as a parameter in controlling gas extraction. The throttle is configured to ensure that there is at least some flow of landfill gas from the landfill to a gas output throughout operation. The extraction system provides an efficient system for landfill gas extraction, while mitigating a risk of creating undesired or unpleasant conditions and/or of violating regulations during operation.
