Abstract
The invention belongs to the field of rock mass engineering monitoring, and provides a heaving floor monitoring method. The heaving floor monitoring method includes that before a heaving floor is transformed, a roadway is stretched across, process monitoring floor groove is excavated, and a floor rock stratum excavation section is formed. Features and conditions of stratification distribution, layering thickness and a structure of floor rock stratums are measured, and the process of transformation of the floor rock stratums is continuously observed. After the heaving floor is transformed, a comparison floor groove is excavated, and an excavation section is formed after the floor rock stratums heave naturally and transform. Features and conditions of floor rock stratums in the excavation section are measured after transformation, the features and the conditions are compared with the measuring result of the process monitoring floor groove for analysis, and essence that the floor rock stratums heave and transform is obtained. By monitoring the conditions of heaving and transformation of the roadway floor rock stratums, and the novel operable method capable of revealing the essence and mechanization of the heaving floor is provided, facilitate breakthrough of a heaving floor theory technology system and provides reliable foundation for solving of the problem of the heaving floor.
Description
Technical field
The invention belongs to rock mass engineering project monitoring field, particularly relate to a kind of pucking monitoring method.
Background technology
By the impact of mining operation, tunnel roof and floor and two helps rock mass produce distortion and produce displacement in tunnel, and namely the phenomenon that roadway floor upwards swells is referred to as pucking.The drift section that pucking causes reduces, hinder transport and pedestrian, obstruction mine ventilation, make many mines have to drop into a large amount of man power and materials and do the interim work for the treatment of such as " digging the end ", serious meeting causes scrapping of whole piece tunnel, produces very large restriction to the production in mine with safety.
For a long time, domestic and international many experts and scholars have done a large amount of research work to coal mine roadway pucking mechanism and control technology, propose many pucking control technologys.Research shows, cause a lot of because have of Floor Heave in Roadway, wherein comparatively outstanding several factors are floor strata character, surrouding rock stress, the effect of water reason, rock mass strength and ground temperature etc.The method of effective floor lift control is roughly divided into two classes: a class prevents, and namely takes measures pucking amount to reduce in the scope of permission; Two is remove pucking, and the part rock that tunnel has been occurred pucking is removed, and recovers drift section and amasss.
Because the generation of pucking can bring impact to a certain degree to the safe and efficient production in colliery, therefore, be subject to the most attention of colliery engineering technical staff, obtain and study comparatively widely.At present, people are according to the different mechanical characteristics of roadway floor, pucking mechanism is idealized as 4 kinds of different modes, that is: the squeezing flow pucking (pseudoplastic fluid ejector half pucking) in soft broken base plate, the bend folding pucking in lamelliform base plate, the shearing changing of the relative positions pucking in complete thick-layer shape base plate, the water swelling pucking etc. in swell potential index.But, actual conditions are: objective geological conditions is of a great variety, and complexity adaptive system multi-form often, seldom there is the ideal conditions of applicable above-mentioned 4 types, the pucking occurred in actual tunnel also varies, be difficult to explained by 4 kinds of ideal type mechanism, especially participating in Failure type etc. that the scope of the floor strata of pucking deformation failure and this scope rock stratum occur is one of pucking major obstacle of preventing theory and technology to be difficult to make a breakthrough for a long time.
Summary of the invention
Embodiments provide a kind of pucking monitoring method, be intended to cause theory to lose contact with reality to the over-simplification of the objective condition of pucking phenomenon in solution prior art, do not monitor the real processes mechanism problem that rock stratum base plate bloats distortion.
A kind of pucking monitoring method, described method comprises:
Before pucking distortion occurs, across roadway excavation process monitoring base tub, form floor strata excavation section, described process monitoring base tub is for monitoring the process of floor strata generation pucking;
Measure the bedding distribution of the floor strata in described excavation section, the characteristic state of lift height and structure, and the deformation process of floor strata described in Continuous Observation;
After pucking distortion occurs, excavation comparison base tub, formation floor strata bloats the excavation section after distortion naturally, and described comparison base tub is for monitoring the feature after floor strata generation pucking;
Measure the characteristic state of floor strata in the excavation section after described distortion, and be analyzed with the observed result of described process monitoring base tub, obtain the essence that floor strata bloats deformation failure.
The embodiment of the present invention bloats deformation by monitoring rock stratum, tunnel base plate, a kind of practicable new method that can disclose pucking essence mechanism is provided, promote that pucking theory and technology system makes a breakthrough, and provide sound and reliable foundation for solving pucking phenomenon.
