Abstract: The present invention addresses the current situation where, in the existing mobile phone cloud account positioning technology, even if the location of a stolen mobile phone is easily obtained, it is difficult to make the illegal possessor return it. Innovative thinking is used to supplement and technologically upgrade the existing functions of the mobile phone cloud account. The specific solution is to expand multiple remote-control menus and signaling for the mobile phone on the mobile phone cloud account client and develop corresponding running programs on the mobile phone side. The present invention also involves the quick guide setting of the mobile phone cloud account, the quick setting of the loss report number, and the use of voice robots to prevent harassing calls, bringing a quiet and convenient intelligent technology experience to mobile phone users.

Abstract: 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.

Abstract: Provided is a method of mining a single steeply-inclined thick coal seam, which belongs to the mining engineering field. The mining method includes: carrying out one transport crossheading along a floor of the coal seam to constitute a production system together with rises on both sides of a district; arranging a top-coal caving hydraulic support along a thickness of the coal seam in the transport crossheading, with a cyclic advance interval being 1.0 m; maintaining one section of return air channel close to a side of a roof that is in a gob and behind the hydraulic support. In a case of mining, caved coals fall on a scraper conveyer and transported through a belt conveyer. Fresh air flow required for a working surface enters the transport crossheading through a district transport crosscut and a track rise, and then enters the return air rise through the return air channel after washing the working surface. A unique return air channel is adopted.
