Abstract: The present disclosure provides a two-stage blade adjusting device for a counter-rotating axial flow fan. A blade adjusting operation shaft is adjusted to drive a pair of bevel gears to transfer power to a threaded pair coaxial with a transmission shaft, the threaded pair transforms rotary motion of the bevel gears into linear motion to push thrust discs in hubs, the blade installation angle of a first impeller is thus adjusted, and a spacer bush transfers the power to adjust the blade installation angle of a second impeller, so that synchronous adjustment of two-stage blade installation angles is realized. The device is simple and compact in structure and low in manufacturing and maintenance cost, and can be widely applied to large, medium and small counter-rotating axial flow fans.

Abstract: A method for recovery of residual coal pillars by freezing accumulated water in room-and-pillar mining areas is provided. A feasibility of repeated mining of residual coal pillars in room-and-pillar goafs is distinguished based on production data and exploration data of a mine. An accumulated water in the room-and-pillar mining areas is frozen to replace a paste filling material, which envelopes collapse roofs and gangues in the room-and-pillar goaf as a whole. The room-and-pillar goaf is filled with a frozen ice body. Roadways and mining faces are arranged in the frozen ice body. Coal cutter cuts the residual coal pillars and the frozen ice body. With the advancing of the mining face, the residual coal pillars are gradually recovered and melted water after the cutting is pumped out.

Abstract: An integrated device and a method for continuously capturing, storing and separating a flue gas in an underground rock stratum are provided. An injection well, a monitoring well and an emission well are arranged in sequence at locations from near to far from a flue gas emission source. The injection well, the monitoring well and the emission well are respectively drilled to different depths in a storage rock stratum. A horizontal injection channel is arranged at bottom end of the injection well. During migrating the flue gas in the storage rock stratum, CO2 and sulfur nitride are absorbed by a rock porous medium and gradually enriched, and meanwhile, the CO2 and sulfur nitride, after chemically reacting with water, minerals and biomass in a rock, are gradually mineralized to achieve storage; and separated N2 is gradually migrated upwards to the emission well to achieve separation.
