Abstract
The utility model discloses a delay filling original roadway coal-pillar-free gob-side entrydriving system which comprises a filling system, an upper-section haulageway and a lower-section air return roadway. The operating method comprises the following steps: filling paste or paste-like material or gangue or high-water material in the haulageway behind an upper-section working face by the filling system according to the geological conditions of different coal seam roofs and coal seam floors; tunneling the lower-section air return roadway along the lower edge of the upper-section haulageway filled body after the upper section haulageway is completely filled and reaches a certain strength and an overlying layer on the upper-section haulageway is stable; and finally, replacing the coal pillars by utilizing the upper-section haulageway filled body so as to achieve an effect of isolating an upper-section goaf and bearing a part of weight of the overlying layer. Therefore, the aim of safe, economic and high-efficiency roadway mining is reached.
Description
Technical field
The utility model relates to the former tunnel of a kind of delay filling without coal column gob side entry driving system.
Background technology
The cut coal conventional method of resource of China is reserved coal pillar between upper and lower section, the goaf with reserved coal column isolation upper curtate, prevent goaf coal nature, leak, gas overflowing etc. this give birth to the generation of disaster.For improving coal recovery rate, China often adopts gob side entry retaining and gob side entry driving technology to reclaim to greatest extent coal column.Edge air gallery technology difficult point is in goaf, to build artificial wall, and stays not easy care of impact that the tunnel of establishing adopted rear mine pressure.Gob side entry driving technical disadvantages is to stay the fender of establishing certain width to isolate upper curtate goaf, to greatest extent reclaiming coal resource.Be badly in need of a kind of can realization without coal column for this reason and excavate the tunnel method for digging that tunnel can reduce again road maintenance rate, realize the efficient back production of safe coal.
Utility model content
The object of the utility model embodiment is to propose the former tunnel of a kind of delay filling without coal column gob side entry driving system, according to different roofs and the geological conditions of seat earth, by filling system, utilize lotion or like lotion or spoil or high-water material, the haulage drift at upper curtate work plane rear is carried out to filling, until the filling of upper curtate haulage drift complete reach and some strength and upper curtate haulage drift overlying rock reach stable after, the driving that carries out lower curtate return aircourse along upper curtate haulage drift obturation, reaches the object that safety economy efficiently excavates tunnel.To achieve these goals, the utility model adopts following technical scheme: the former tunnel of a kind of delay filling, without coal column gob side entry driving system, comprising: filling system, comprises filling pumping plant, filling pipeline, filling template; Upper curtate haulage drift, comprises hydraulic prop, protects lane equipment; Lower curtate return aircourse, comprises heading equipment and support apparatus; Hydraulic prop Ji Hu lane equipment is withdrawn in time work plane rear upper curtate haulage drift after upper curtate working face extraction, for tunnel filling ready; The filler of filling pumping plant pumping carries out filling by filling pipeline and filling template to upper curtate haulage drift; Heading equipment until the filling of upper curtate haulage drift complete and reach some strength and tunnel overlying rock reach stable after, along upper curtate haulage drift obturation lower limb, carry out the driving of lower curtate return aircourse, and utilize in time support apparatus to carry out the supporting of lower curtate return aircourse.
Preferably, described hydraulic prop Ji Hu lane equipment is withdrawn in time work plane rear upper curtate haulage drift after upper curtate working face extraction, for tunnel filling ready.
Preferably, the filler of described filling pumping plant pumping carries out filling by filling pipeline and filling template to upper curtate haulage drift.
Preferably, described heading equipment until the filling of upper curtate haulage drift complete and reach some strength and tunnel overlying rock reach stable after, along upper curtate haulage drift obturation lower limb, carry out the driving of lower curtate return aircourse, and utilize in time support apparatus to carry out the supporting of lower curtate return aircourse.
Establish or tunnel lower curtate tailgate and compare with existing staying, the utlity model has following advantage: the former tunnel of delay filling that the utility model is addressed is without coal column gob side entry driving method, specifically there are filling system, upper curtate haulage drift, lower curtate return aircourse, by filling system and upper curtate haulage drift preparation, filling operation and lower curtate stope drift active workings excavate, support work on time and space rationally, realize the former tunnel of delay filling without coal column gob side entry driving.First-selected hydraulic prop Ji Hu lane equipment is withdrawn in time work plane rear upper curtate haulage drift after upper curtate working face extraction, for tunnel filling ready.Then the filler of filling pumping plant pumping carries out filling by filling pipeline and filling template to upper curtate haulage drift.Last heading equipment until the filling of upper curtate haulage drift complete and reach some strength and tunnel overlying rock reach stable after, along upper curtate haulage drift obturation lower limb, carry out the driving of lower curtate return aircourse, and utilize in time support apparatus to carry out the supporting of lower curtate return aircourse, finally utilize the filling of upper curtate haulage drift to replace coal column to play the effect that part overburden weight is born in isolation goaf simultaneously, reach the object of safety economy high efficiente callback coal resources.
