METHOD OF DEVELOPMENT OF FLAT DIPPING BEDS OF MINERALS Russian patent published in 2009 - IPC E21C41/00 

FIELD: mining.

SUBSTANCE: invention refers to mining and can be implemented at development of flat dipping beds of minerals, mainly coal beds, in cleared pit walls and in places of bed exposure. Mining of the bed of mineral is performed by means of complex of deep development of beds - CDDB - of mining chambers. Transporting mineral from mining chambers to surface is carried out via a box multi-link transporter. Massifs of mineral are left between mining chambers. Places of location and amplitudes of disjunctive geological disturbances of uplift type are determined within the ranges of the mined region of the mineral bed. The mining chambers are parallel to fractures of impenetrable disjunctive geological disturbances. Massifs of useful mineral are left under fractures of disjunctive geological disturbances. Disturbances with amplitudes of vertical upheaval of the bed bigger, than their maximum permissible values, are considered as impenetrable disjunctive geological disturbances. Transfer of CDDB at such disturbances is impossible because of dangerous bends in a vertical plane of the box multi-link transporter causing deformation and destruction of the transporter. Maximum permissible values of amplitudes of vertical upheaval of the bed are accepted as not exceeding product of distance from the beginning of the mining chamber to the disjunctive geological disturbance by tangent of maximum permissible value of an angle between the plane of a working platform, whereon CDDB is mounted, and the box multi-link transporter; when the product is exceeded, deformation and destruction of the box multi-link transporter occur.

EFFECT: increased efficiency with implementation of CDDB and reduced production costs and losses of mineral.
