Coal mining solid filling method
InactiveCN101586460AHelps control sinkingEasy to useUnderground miningSurface miningSolid massFilling materials
A coal mining solid filling method comprises following steps: using the stacked solids on the ground as the filling materials for the working surface goaf, directly putting the solid filling materials from the ground to a belt conveyor in the underworkings by a perpendicular feeding well, transporting to the end of a coal face through the underground belt conveyor, reloading the solid filling materials to a solid filling mining conveyor hung under a back tail beam of a self-impacting type filling hydraulic support by a self-moving type filling material reloading machine. In the process of mining work, the coal is mined and the filling materials are filled on the bottom; and the solid filling materials are compacted by means of a compactor of the self-impacting type filling hydraulic support. The method solves the problem of coal compaction under the building and low coal recovery.

Multi-source positioning system for work machines
ActiveUS7139651B2Improve positionIncrease valueAnalogue computers for trafficPosition fixationAccelerometer dataKaiman filter
A three-dimensional and a two-dimensional GPS unit periodically provide coordinate positions of points on the work machine and are combined with a Kalman filter to produce a point of reference on a work machine. The point of reference is improved by combining the position with an inertial position derived from accelerometer data in another Kalman filter. Additionally, the two-dimensional GPS unit provides a heading that is combined with an inertial orientation derived by the angular rate from a gyroscope in another Kalman filter to produce a precise orientation estimate. Inclinometers provide pitch and roll of the work machine. With the point of reference, orientation estimate, pitch, roll and known geometry of the work machine, the GPS unit calculates the location and orientation of machine components and continuously tracks its movement throughout the mine. Additionally, the accelerometers and gyroscope provide position and orientation when the GPS units are inoperable.

The invention discloses an opencast mine end slope near-slope mining method. During an opencast mining process, for integral side slopes of end slopes on two horizontal sides of a mining field, near-border mining is carried out according to a stable angle alpha as in an initial design; according to a timeliness slope principle, inner dump is followed up in time; a pit bottom distance is shortened to a minimal safety distance Dmin required by mining, and integral height H of the side slope of the end slope is reduced; according to a side slope stable condition, the side slope angle is increased to beta; and near-slope mining is realized. The height of inner dump bottom layer slope-pressing step is 2-3 times that of mining working slope step. Stripped soil and rock are transported to the inner dump bottom layer slope-pressing step through a built soil-discharge bridge. With the method provided by the invention, side slope angle can be increased on a basis that slope end stability is ensured. Therefore, end slope residual coal can be recovered; stripping ratio can be reduced; and transportation cost can be reduced.
