Kiziyarov O. Justification of the technology parameters of combined hardening roof longwall faces

The purpose of the work is to justify the parameters of the combined technologies of hardening of the roof in the lavas by the nature of the broken array. Research methods: analysis and synthesis of the literature and patent sources, full-scale, laboratory and theoretical studies, as well as the ve-ably-statistical methods of data processing. Results: set the intensity of the influence of fracture height and tree fall at hardening sprayed bonding composition on the stability of the roof becomes exposed to the working face; obtained depending on the definition of the permeability coefficient of the roof in an unstable lava ahead of stope and the depth distribution of the bonding at hardening unstable roof in the lava injection Given the uneven penetration of the array along the hole. Schemes of the combined hardening unstable roof in the lava, and the parameters are defined by their application. Designed less Methodical guidance on the application of technology combined hardening of the roof in the mine clearing faces SE Luganskugol. Sphere (industry) use of - in the mining industry in the development of amendments to the model passports coal mining, fixtures and roof control stope, in scientific-research and design institutes mountain areas, in schools.
