Description
Technical field
The invention belongs to coal mining technology fields, and in particular to a kind of to replace coal column using pit waste filling mining
Method.
Background technology
Currently, China " under three " press coal amount huge, the coal-mining method under building, under railway and under water body is referred to as " three
Under " mine, surface subsidence, generally manages goaf top plate using placement method in order to control.By the difference of coal-mining method, filling
Method has house column type filling mining and longwall filling mining；By the difference of filler, there are waste filling, paste body filling and height
Several placement methods such as water filler filling.
Down-hole spoil quantum of output is huge, and a large amount of flyash, the haline water of mating power plant's generation, coal are electrical integrated in addition
Enterprise need to handle a large amount of waste, waste water every year, at present processing method generally existing processing capacity it is limited, can not integrated treatment,
The problems such as cost is excessively high and violates environmental protection policy, it is therefore necessary to seek a kind of method of comprehensive utilization of efficient green.
Traditional placement method cannot achieve the comprehensive utilization of fly ash in electric power plant, haline water and mine spoil, novel filling side
Method need to meet while integrated treatment waste, waste water, realize the replacement exploitation of coal column, improve resource recovery, increase economical
Benefit.
Invention content
The present invention provides a kind of methods for exploiting displacement coal column using spoil strip filling, while pit waste utilizes
Underground coal column can be replaced, improve resource recovery and economic benefit.
Using following steps：
1）The transportation roadway dug in advance, cut eye, air return lane constitutes ventilation circuit, form full exhaust ventilation.If coal column is divided into
Dry exploitation band, rationally determines stripe cell length and width, and number consecutively is in order according to buried depth and mining height（1）,
（2）,（3）,（4）,（5）…….
2）Stripe cell is exploited using continuous milling machine, is exploited successively（1）,（3）,（5）,（7）... unit.Continuous milling machine uses certainly
Dynamic mode of coalingging, is completed the reprinting and transport of bastard coal by mine shuttle car, rubber conveyer, when coal mining, needs local fan ventilation.Band
Unit mine after, top plate and two help according to design of its support using roof-bolter carry out bolting with wire mesh.
3）Stripe cell first closes transportation roadway end seal with after two stope drift active workings perforations, and fire dam uses mode of building a wall, and
In outer side back plank, monomer is beaten with proof strength.Ground spoil is dropped naturally through waste shaft, is buffered through waste bin, and spoil is passed through
Belt conveyor reaches filling band, is then shed, is accumulated in stripe cell extraction space from return air heading using throwing cash machine
Spoil.
4）After the completion of throwing cash, stripe cell air return lane end seal is closed using the same manner, PE Grouting Pipes are reserved on wall, are
Ensure that slurries are full of spoil crack, fully connect top, in the filling pre-buried two groups of high-low-position Grouting Pipes of unit.
5）At ground slurry preparing station by flyash, haline water in mass ratio 1：1~1：Pulverized fuel ash slurry, pipeline is made in 0.6 proportioning
It is delivered near underground filling point, in underground, suitable position filling pumps curing agent slurries processed, the two in mass ratio 1：1~1：0.6
Proportioning is right successively after mixer mixes（1）,（3）,（5）,（7）... unit is filled.
6）It waits for（1）,（3）,（5）,（7）... it is then right after unit strength of filling mass reaches requirement（2）,（4）,（6）,
（8）... unit repeats 2）-5）Step, 2）Step and 3）,4）,5）Step can be synchronized in different units and be carried out.
7）And so on, until stripe cell exploitation, the filling of entire coal column finish.
The beneficial effects of the invention are as follows：
1, a large amount for the treatment of of Power flyash, haline water and mine discard spoil, reduce ground stacking and pollution environment.
2, the mine resource rate of recovery is improved, mine service-life is extended.
3, by surface settlement control in prescribed limit, ground is avoided to move, increases economic benefit.

Specific implementation mode
Below in conjunction with attached drawing 1-3, the invention will be further described.It is a kind of to utilize spoil strip filling exploitation displacement coal column
Method, the scheme exploited using underground coal mine strip filling, specific implementation mode is as follows：
1）The transportation roadway 1 dug in advance, cut eye 2, air return lane 3 constitutes ventilation circuit, form full exhaust ventilation.Coal column is divided into
Several exploitation bands rationally determine stripe cell length and width, and number consecutively is in order（1）,（2）,（3）,（4）,
（5）…….
2）Stripe cell is exploited using continuous milling machine, is exploited successively（1）,（3）,（5）,（7）... unit.Continuous milling machine 4 uses
Automatic loading of coal mode is completed the reprinting and transport of bastard coal by mine shuttle car 6, rubber conveyer 7, when coal mining, needs local fan ventilation.
Stripe cell mine after, top plate and two help according to design of its support using roof-bolter 5 carry out bolting with wire mesh.
3）Stripe cell first closes transportation roadway end seal with after two stope drift active workings perforations, and fire dam uses 8 modes of building a wall,
And in outer side back plank, beat monomer with proof strength.Ground spoil is dropped naturally through waste shaft 14, is buffered through waste bin 15, is led to
It crosses spoil belt conveyor 9 and reaches filling band, then produced in space toward stripe cell from return air heading using throwing cash machine 10
It sheds, accumulate spoil.
4）After the completion of throwing cash, stripe cell air return lane end seal is closed using the same manner, PE Grouting Pipes 18 are reserved on wall,
It is full of spoil crack for guarantee slurries, fully connects top, in the filling pre-buried two groups of high-low-position Grouting Pipes of unit.
5）At ground slurry preparing station 16 by flyash, haline water in mass ratio 1：1~1：Pulverized fuel ash slurry is made in 0.6 proportioning, manages
Road 11 is delivered near underground filling point, suitable position filling 12 curing agent slurries processed of pump, the two in mass ratio 1 in underground：1
~1：0.6 proportioning is right successively after the mixing of mixer 17（1）,（3）,（5）,（7）... unit is filled.
6）It waits for（1）,（3）,（5）,（7）... it is then right after 13 intensity of unit obturation reaches requirement（2）,（4）,（6）,
（8）... unit repeats 2）-5）Step, 2）Step and 3）,4）,5）Step can be synchronized in different units and be carried out.
7）And so on, until stripe cell exploitation, the filling of entire coal column finish.
