INTEGRATED METHOD OF THE preliminary degassing of coal seams, the developed space and the formation of satellite and manage ROOF COLLAPSE OF SEVERE

摘要

An integrated process for pre-degassing working coal seam gob and layers satellites and controlled caving heavy roof comprising conducting field preparatory drifts / incline, drilling fan wells into the soil and roof formation of special reservoir workings, as well as the long holes toward the goaf formation of advanced generation, smooth landing of the roof due to safety zhestkopodatlivyh pillars, for the implementation of advanced torpedo with cracks of the building; characterized complexity measures: wells are common for both degassing and for the torpedo, the creation of safe zhestkopodatlivyh pillars promotes directional collapse console and includes the risk of failure torpedo, the location of the torpedo-degassing wells provides longitudinal and lateral collapse hanging console when reaching its ultimate length; and in that the degassing of the roof takes place through the borehole, both before and after the torpedo at the top.
