Description
Technical field
This utility model relates to sealing of hole fixture fields, especially relates to a kind of mash gas extraction drilling cuttings backfill pouch slip casting type
Hole packer.
Background technology
Gas drainage under suction is currently to reduce one of coal-face gas density, the most effective measure implementing region protrusion-dispelling, watt
This gas drainage results, depends greatly on method for sealing and sealing quality.
The gas hole sealing device that colliery is commonly used at present mainly has polyurethane sealing aperture apparatus and cement mortar hole sealing device；
For polyurethane sealing aperture apparatus, owing to polyurethane material anti-pressure ability is low, easily cause sealing insecure, cause later stage gas to take out
Put concentration to drastically reduce, sealing of hole failure；For cement mortar hole sealing device, its cement mortar uniaxial compressive strength is higher, and tool
There is certain mobility.But cement mortar sealing of hole uses ordinary cement, need relatively in injecting gas pumping hole due to cement
Solidification, and the volume contraction easily caused due to the reason such as variations in temperature, environmental drying in its process of setting for a long time,
Can cause to a certain extent and block unsuccessfully.
No matter polyurethane sealing of hole or cement mortar sealing of hole, cost is the highest, and raw material transport and store the most pretty troublesome,
Needing to install rational proportion during use and can be only achieved optimum efficiency, injection slurry thickness, moisture can not be too many, otherwise affects coagulability
Energy and setting time.And, after using polyurethane sealing aperture apparatus and cement mortar sealing of hole, can remain in coal seam, increase exploitation
Difficulty, affects coal quality.
