Abstract: The present invention discloses an experiment device and a method for detecting abrasion of a conveyer. The device comprises a rack, a reciprocation sliding mechanism, a speed adjusting mechanism and a crankshaft, wherein the reciprocation sliding mechanism comprises scrapers and scraper chains; the scraper chains are arranged between an upper-layer scraper and a lower-layer scraper; the speed adjusting mechanism comprises a motor, a friction driving wheel and a friction driven wheel; the motor is connected with the friction driving wheel through a motor shaft; the friction driving wheel slides on a shaft in an axial direction; speed adjustment can be achieved by changing the distance between the centers of the friction driving wheel and the friction driven wheel. Due to the adoption of the speed adjusting motor, the speed can be precisely controlled; as the crankshaft is arranged on the shaft of the friction driven wheel and connected with the reciprocation sliding mechanism through two connecting rods respectively, the scraper chains and chain devices are driven in a reciprocation manner at the adjusted speed, so as to realize reciprocation motion of a material inside a groove. The present invention can simulate friction between friction pairs of the actual conveyer well when the material is conveyed, and avoid experiment on a complex conveyer structure.

Abstract: A ventilation method for a high gas working face based on alternating intake and air return in a mine gallery is provided. In this method, an isolated island working face is divided into several sections along a strike direction. A coal pillar is alternately set as a conventional section and a gas-drainage section. Opposite coal pillars in the two mine galleries within the same section are respectively used as the conventional section and the gas-drainage section. Two mine galleries on both sides of the isolated island working face are alternately used as an intake gallery and a return gallery. The coal pillar at the side of the mine gallery as the return gallery is the gas-drainage section. A gas-drainage hole communicating a goaf is provided in the gas-drainage section, so that gas in the goafs at two sides of the isolated island working face can be extracted alternately.

Abstract: An I-patterned filling method for an initial stage of coal mining based on roof fracture characteristics is provided. A relationship between an overburden load borne by a main roof and an overhang size is determined based on principle of virtual work and a surgery theory when an overhang distance of the main roof reaches an initial weighting interval to enter a plastic limit state with an advance of a working face to obtain the initial weighting interval. An initial fracturing interval of an immediate roof is obtained in the same way. According to a subsidence law of the main roof in an inverted hip roof form, the filling is performed at a key position around an internal plastic hinge line through I-patterned three-strip filling. Size parameters of the I-pattered filling are designed to prevent the immediate roof and the main roof from being fractured.
