Abstract

The invention discloses a solid filling inclined material feeding method, which comprises the following steps: an inclined shaft is constructed in the direction of coal seam mining, a material conveying passage is mounted in the inclined shaft, a feed bin communicated with the outlet of the inclined shaft is constructed at the upper part of a transportation roadway, and a feeding machine connected with a feeding belt machine is mounted at the outlet of the feed bin; when the inclined shaft performs feeding, the solid filling material is conveyed into the feed bin quickly through a vibrating motor, transferred to the feeding belt machine via the feeding machine, and conveyed on the coal face via the feeding belt machine. The solid filling material can slide downwards quickly and can satisfy the real-time controllability of speed, and the defect of batch charging of a batch charging system is avoided. The method is simple, convenient to operate, high in production efficiency, low in cost and excellent in use effect.

Description

A kind of solid filling inclination feeding method
Technical field
The present invention relates to a kind of solid filling inclination feeding method, be particularly useful for the solid filling goaf coal mining activity under the coal mine.
Background technology
Along with expanding economy, the progress of society, CSR is reached common understanding; be the protection scarce resource; country puts into effect a series of policies, impels enterprise to change " predation " formula mining type in the past, forces enterprise to improve resource recovery rate, associated resources utilization rate." three times " press the exploitation of coal is the major issue that merits attention always, and according to incompletely statistics, the present China only mine main of coal mine under the unified-allocation system " three times " presses coal just to reach 137.9 hundred million t, wherein builds down 94.68 hundred million t, accounts for 69% of stagnation pressure coal amount.Be enterprise's input-output efficiency, prolongation mine service-life, the minimizing wasting of resources that improves enterprise, improving the mine rate of extraction is the key subjects of pendulum in face of us.Simultaneously, a large amount of solid waste spoils is discharged in the colliery aborning, and traditional mode is directly to be stacked at the face of land, forms the distinctive topographical features in colliery " building "-hillock.According to statistics, the spoil of whole nation accumulative total stacking over the years at present is about 4,500,000,000 t, and larger hillock has more than 1600, and land occupation is 1.5 ten thousand hectares, and accumulating amount also increases with the speed of 1.5-2.0 hundred million t every year.In addition, a large amount of flyash of discharging during coal field power plant for self-supply produces, discharge value over the years reaches more than 500,000,000 t, and annual newly-increased 5-7 10,000,000 t.Any discharging of these solids causes serious threat for the ground ecological environment; at these problems; from realizing the purpose of resource and environment coordinated development, seeking rational exploitation and utilization mineral resources, protection face of land building and groundwater resources and protection or transforming face of land technological approaches becomes inevitable.The problem that " three times " press coal to become the task of top priority to solve with hillock, and how simply, fast, effectively the packing job of finishing the goaf is a great problem.Because the top board in goaf just was subjected to the effect of overburden pressure before filling, can produce bigger sinking, influence packing job and the filling effect in goaf, therefore develop and a kind ofly can guarantee the safety in coal work space can realize that again the support of solid waste filling in the goaf is one of key that realizes this technology at the exploitation work plane.Application number is that 200910033721.1 disclosed a kind of solid filling method and application numbers of mining are the big vertical depth solid feeding system of 200920046255.6 disclosed a kind of filling coal minings, the perfectly straight mode that taps into capable vertical feeding has obtained good effect, but this feeding mode that carries out solid material is the down-hole of directly discarded object being rendered to hundreds of rice from ground, the input mode of material is too big to the impact of snubber like this, the speed control of bad realization material.
Summary of the invention
Technical problem: the objective of the invention is to overcome the weak point in the technology, provide a kind of simple to operate, throw in the solid filling inclination feeding method of material continuously.
Technical scheme: solid filling inclination feeding method of the present invention comprises the steps:
A. in surface plant, make a call to an inclined shaft that leads to above the transportation lane to the working seam direction, or utilize original in the inclined shaft that transports the top, lane, defeated material passage is installed in inclined shaft, described defeated material passage comprises that base, interval are located at the spring base on the base, the spring base upper support has slideway, the top of slideway is provided with lid, is interval with many vibrating motors on the lid;
B. construction exports the feed bin that is connected with inclined shaft above the transportation lane, and lays the feeder that links to each other with the feeding belt machine in the exit of feed bin;
During c. by the inclined shaft feeding, open vibration motor, the solid filling material in the slideway is advanced in the feed bin under the fast vibration under the effect of vibration motor and spring base, transfers on the feeding belt machine through feeder, is delivered to coal-face by the feeding belt machine.
The angle of inclination of described inclined shaft is 14~30 °; The distance that described interval arranges vibrating motor is 5m~10m.
Beneficial effect: the present invention utilizes the solid material of ground accumulation as the attal in work plane goaf, the solid filling material is rendered to rubber conveyer in the underworkings from ground by the inclination well that feeds intake, be transported to coal-face by the down-hole rubber conveyer again.The feeding mode that tilts has great importance for existing inclined shaft colliery, western part as feeding mode, or for newly-built the describing the scenery in western part.Utilize sliding and the weight deadweight of slideway self, the real-time controllability of speed can be slided and can be satisfied to realization fast, avoided the defective of the system that delivers directly.Its method is simple, and is easy to operate, the production efficiency height, and cost is lower, has practicality widely.
