Description
Technical field
The present invention relates to paste body filling monitoring technical field, refer to a kind of stope paste filling material heat-water-Li-change many performance monitoring devices especially.
Background technology
Lotion is the toothpaste-like high density non newtonian suspending liquid that one or more materials and jelling agent are composited.Lotion can by pipeline pumping or self-flowing pastefill to down-hole.After ore extraction is complete, generally will build filling counterfort before filling, the lotion material flowed at the beginning of filling makes barricade unstability be a potential danger, and its consequence is very serious, may cause personnel and property massive losses.The stability of barricade is paste body filling security implementation inalienable part, and in general, people utilize the engineering experience in other mine to make barricade, and the actual conditions of self filling of less consideration.Barricade will be caused like this to make too conservative, or barricade lost efficacy.Some mines are in order to ensure the security of barricade, and generally divide filling several times in a stage casing, first stage filling only has 5 ~ 7m, treat first stage casting resin maintenance certain hour, have certain mechanical stability, then carry out the continuous filling of remainder stope.But in actual filling, due to the harden(ing)by itself of lotion material and the arching effect with country rock, perhaps barricade pressure be less than predicted value.If actual pressure during barricade filling accurately can be judged, filling will change continuous filling into stage by stage, and also can ensure the security of barricade simultaneously, then can shorten loading time; Such as certain ore deposit external changes continuous filling into by filling stage by stage, and loading time shortens about 20%.
In addition, lotion material in stope due to pore water seepage flow, casting resin volume becomes large (compared with laboratory experiment), and the change of the factor such as curing temperature, humidity, laboratory experiment proportioning intensity level and underground stope intensity level are perhaps not identical.Directly get at underground stope that filling body examination intensity cost is high, difficulty large, feasibility is poor.The mechanical property of lotion material depends on hydrated reaction of cement, and therefore, the mechanical property of lotion can be developed by lotion internal chemical reaction monitoring and hydraulic performance and carry out anticipation.Like this, just can be analyzed the mechanical property of actual filling stope lotion material and laboratory experiment, for mine management person adjust in time material mixture ratio, save filling cost, design more safe and reliable obturation there is great importance.
To sum up, Real-Time Monitoring carries out for barricade pressure in lotion material maintenance processes and stowing operation etc. extremely important.But, at present for this aspect research or report less.The present invention is intended to propose a kind of stope paste filling material heat-water-Li-change many performance monitoring devices and using method thereof, both may be used for lotion material inner, also may be used for barricade pressure monitoring.For improving paste body filling mining efficiency and providing reference safely.
