The invention discloses a remained small
coal pillar comprehensive mechanized
coal mining supporting structure and a construction method. The remained small
coal pillar comprehensive mechanized
coal mining supporting structure and the construction method comprises a narrow
coal pillar arranged between a current stope working face and an adjacent stope working face, one side of the narrow
coal pillar is provided with a filling body, and the adjacent stope working face is also provided with a roof presplitting
cutting line; the construction method of the remained small
coal pillar comprehensivemechanized
coal mining comprises the following steps that before the
coal mining, an air return way, a
haulage gate, and an auxiliary
haulage gate are constructed; the roof presplitting
cutting line of the current stope working face is constructed in the auxiliary
haulage gate; then the filling body is constructed synchronously with a head coal mining. The remained small coal pillar comprehensivemechanized coal mining supporting structure and the construction method solves the problems of
gangue darting into a lane in a worked out section, roof
bolting accident of the auxiliary transport chute, and the leakage of the narrow coal pillar in the current stope working face; and the mining influence to the auxiliary transport chute caused by the stope working face is weakened, cost of maintenance of the lane is reduced, and
recovery coefficient of coal resource is enhanced; and the remained small coal pillar comprehensive mechanized coal mining supporting structure and the construction method can be applied to most geological mining conditions and has a great significance to promote and achieve safe and efficient mining of coal mine.
