Description
Technical field
The present invention relates to mine fire prevention technical fields, more particularly to a kind of anti-running pulp system of mine slip casting pipeline.
Background technique
Fire extinguishing engineering is the most important thing of Safety of Coal Mine Production, can be gone out by slurrying slip casting with effective solution coal mine is anti-
Fiery problem.Slip casting preventing and extinguishing fire technology has the characteristics that safe and reliable, economical and practical, is at home and abroad widely applied.
Slip casting preventing and extinguishing fire technology is that a certain concentration is made by certain proportion in water and non-flame properties solid material (yellow mud or flyash)
Slurries, being delivered to using feed pipe for mortar may occur or have occurred and that the place of spontaneous combustion, to prevent spontaneous combustion or stamp out a fire.
Slurries are filled between broken coal or rock crevice, and the solid matter of precipitating can be played oxygen barrier stifled with filling fracture and package float coal
The effect of leakage；Mud plays the role of cooling heat dissipation to coal simultaneously.The key of this technology is oxygen barrier resistanceization, therefore slip casting is prevented going out
The content of solid material that is, concentration of hydraulic mixture is very big to the influential effect of slip casting fire extinguishing, the bigger effect of concentration of hydraulic mixture in mud when fiery
Fruit is better.
In mine slip casting fire extinguishing engineering site implementation process, grouting system running pulp happens occasionally, and gives fire extinguishing engineering
Bring very big puzzlement.Grouting system running pulp reason then mainly has following several respects: first is that present in slurry solids material
Particle for a long time wears pipeline, and tube wall is more and more thin, eventually causes broken wall running pulp；Second is that pipeline weld bond cracking causes running pulp；Three
It is since pipeline is shaken, pipeline junction loosens cracking running pulp；Fourth is that O-ring failure causes running pulp at pipeline interface.Current state
Mainly manually the method for inspection slip casting pipeline solves the problems, such as running pulp to interior mine.The method of artificial inspection slip casting pipeline solves to run
Slurry problem, is primarily present following problems:
1. artificial economic cost is big.Work is maked an inspection tour in one group of slip casting at least needs 5 people (3 Ren Dao class Threes, 2 people, which work on regular shifts, to have holidays by turns), by people
Equal annual income 140000 calculates, and every set grouting system at least needs to put into artificial economic cost: 140000*5=700000 member every year.
2. manual patrol effect is poor.Because grouting system running pulp has the characteristics that not timing, erratically etc. randomnesss are big, often
Personnel cannot have found in time when secondary running pulp, lead to large area running pulp, not only cause the waste of mud, but also slurries pour in tunnel
The normal walking and quality standardization in tunnel are influenced, mine side need to be cleared up in arrangement personnel, bring multiple economic loss.
3. the practical grouting amount in goaf can not accurate perception.Traditional goaf grouting amount be by manually estimating roughly,
Inherently error is big for the algorithm, and running pulp amount has also counted the practical grouting amount in goaf together, cause engineers and technicians without
The practical grouting amount in method accurate perception goaf can not work for other goaf fire extinguishings in the same exploiting field of same coal seam and provide
Accurate Technical Reference numerical value.
4. occupational disease is high-incidence.Manual patrol grouting system requires slip casting to make an inspection tour work round-trip walking, underworkings in roadway
Climatic environment is special, and long-term walking is easy to damage personnel joint etc., improves the disease incidence of worker's occupational disease.
5. there are security risks.In order to not influence pedestrian's driving, underground grouting pipeline generally lays coal side at top plate,
Because grouting system running pulp has the characteristics that not timing, erratically etc. randomnesss are big, therefore running pulp once occurs for grouting system, with pressure
The slurries ejection of power is possible to hurt the personnel to walk in tunnel at any time, and there are security risks.

Line leading portion, back segment mud stream magnitude change: running pulp pipeline leading portion mud stream magnitude becomes larger to a certain degree, after running pulp pipeline
Section mud stream magnitude becomes smaller to a certain degree.Bifurcated then occurs for the curve that the data that sensor 202 detects are drawn, as shown in figure 4,
Running pulp pipeline leading portion flow curve is in " to reduce " to a certain degree in tendency, running pulp pipeline back segment flow curve " is increased " to a certain degree
Tendency, since the reduction running pulp pipeline front and rear sections flow curve of same section sensor was in more originally " sparse " state, between two curves
By " rapid drawdown " curve connection, from fig. 4, it can be seen that the central point of its fluctuation range is by Q1 rapid drawdown to Q2.
When there is "off" for n-th section of slip casting pipeline, grouting system pipeline entirety on-way resistance is reduced, therefore before running pulp pipeline
Section, back segment mud stream magnitude change: running pulp pipeline leading portion mud stream magnitude becomes larger to a certain degree, running pulp pipeline back segment mud
Starching flow value is " 0 ".Bifurcated then occurs for the curve that the data that pipeline flow probe uploads are drawn: running pulp pipeline leading portion flow curve
In tendency " is increased " to a certain degree, running pulp pipeline back segment flow curve and X-axis are overlapped, and due to the reduction of same section number of sensors
Running pulp pipeline leading portion flow curve is in " sparse " state more originally, is connected between two curves by " rapid drawdown " straight line.As shown in figure 5,
Before and after pipeline disconnection, flow value is Q1 rapid drawdown to zero by mean value.
