摘要： The invention relates to the longwall face support of an underground mine having supports (plates 1-18), which longwall face support comprises camera housings (35) each having two cameras (36), which record a monitoring area of the face having a plurality of plates in the longitudinal direction of the gallery and the most complete registration possible of the cross section of the gallery. The cameras in a monitoring area are assigned to a common power supply unit (48) for the power supply and are equipped with intrinsically safe electronics. The electronics have a radio device for high-frequency data transfer (transmission and reception) together with antenna 39 (W-LAN antenna) for the wire-free connection to the local camera network (Wireless Local Area Network). Each camera and each camera housing is assigned a camera code and an address code, which is added to the identification data. Each radio device is configured such that data marked with an extrinsic camera code and data and signals marked with an extrinsic address code is emitted to be transmitted following reception.

摘要： Disclosed is a method for designing supporting parameters of a transition support for a mixed mining face of filling and fully-mechanized mining. The method includes: first, determining a total length of a mixed mining working face and a length of a filling section according to requirements of a coal mining production capacity of the mixed mining working face and a filling capacity of the filling section working face; then, establishing a mixed mining numerical model of filling and fully-mechanized mining by using three-dimensional distinct element software, and simulating and calculating a caving height of a roof of a transition section and a stress influence range of the transition section when a filling rate of a mined-out area of the filling section changes; based on a result of numerical simulation and calculation, performing curve fitting according to a correlation coefficient to obtain a functional relationship between the filling rate and the caving height and a functional relationship between the filling rate and the stress influence range of the transition section; and finally designing supporting parameters of a transition support in combination with actual engineering geological parameters. The method can provide a reference for supporting design of a support, and enables a smooth transition between a filling support and a fully-mechanized mining support for a mixed working face, thereby further enriching filling mining theories and expanding the application range of filling mining.

摘要： A method for removing a hydraulic support for solid filling coal mining includes digging a support removing channel (3) in a coal body (2) in front of the hydraulic support (1), and laying a support removing track (4), then removing the hydraulic support from a coal conveying gateway (11) to a track gateway (5), temporary supporting is carried out by matching a single supporting column with a n-type steel beam before each hydraulic support is removed. A supporting roof is reinforced in time by means of erecting a crib (13) and grouting after each hydraulic support is removed, three grouting pipelines (12) are laid after the supports of the whole work surface are removed, and grouting is carried out in the whole finishing cut space. The roof of the support removing space of the work surface is stable so that the hydraulic supports on the work surface of solid filling coal mining are ensured to be safely and efficiently removed.

摘要： A sliding stabilizer is a machine for supporting the roof in the working zone of a mine. A sliding stabilizer operates in tandem with a mining roof support machine. A sliding stabilizer is capable of supporting the mine roof independently of the roof support machine. A sliding stabilizer has a peak roof covering, a flexible sheet that extends toward the roof covering of a support machine, and a rotating retractable leg. The retractable leg rotates from the mineral seam to inside the roof covering of a support machine. The retractable leg propels the peak into the working zone of the shearer. A sliding stabilizer supports a previously insupportable roof.
