METHOD OF DEVELOPMENT OF POWERFUL STEEPLY INCLINED COAL BED IN STRIPES DOWNWARDS Russian patent published in 2014 - IPC E21C41/18 E21C35/24 

Abstract RU 2527852 C1

FIELD: mining.

SUBSTANCE: method of development comprises preparing of the extraction column carrying out conveyor and ventilation drifts, preparing of winning band by performing off end and near slopes along the downwards line at the soil of layer from the conveyor to the ventilation drift on both sides of the band, performing the mounting chamber at the ventilation drift, mounting of sections of aggregated timber in it, coal extraction with low-inclined layers by the shearer of front action and transportation of coal along the bottom hole of self-propelled car to off end slope , in inclination of the extracted layer towards the near slope, or to the near coal chute slope, in inclination of the extracted layer towards the off end slope, change in the direction of inclination of the layer and turn of the combine in the chamber, which is carried out outside of the winning band. And the self-propelled car is equipped with an automated control system. At that from the overlap of each section of the aggregated timber towards the soil layer a signal is given, corresponding to the order number of the timber section, this signal is received by the receiving device mounted on the self-propelled car, and is transmitted to the automated control system. After changing the direction of inclination of the layer setting up of the control system of the self-propelled car is carried out, which, depending on the combination of numbers of the received signals and the degree of loading the body, ensures actuation of actuators of the self-propelled car - movement back and forth, drive-brake, loading-unloading, stop.

EFFECT: increased efficiency and safety of the development of powerful steeply inclined layers due to organisation of the automated control system of the self-propelled car for transporting loosened coal.
