Background technique
Coal mine major accident, including Stope roof collapse accident, bump, mine perviousness, prominent watered-out well etc., mostly with adopt
Dynamic country rock movement is directly or indirectly related to change of stress field (variation including stress intensity, distribution)；On the other hand, in recent years
Due to the needs of large-scale infrastructure construction, there are some major infrastructure projects to pass through mining area successively, how to guarantee great
Mining overburden stability when infrastructure project passes through mining area, not only mining area safety is produced it is significant, but also to ensuring this
A little infrastructure projects are great in construction and the security implications during operation.
Summary of the invention
The purpose of the present invention is to provide a kind of method of determining Underground Engineering Excavation status, beneficial effects of the invention
Fruit is the influence damage envelope that can accurately determine during complex condition mining overburden random motion, is accurately determined
The stress field range being directly linked in mining overburden motion range out, to being embodied as Safety of Coal Mine Production.
The technical scheme adopted by the invention is that:

Method.
Further, the random distribution characteristic of rock mass condition includes discontinuity surface occurrence, mark length, size, spacing, density, opens
Aperture, filler, waviness, roughness, alteration extent, Spatial Coupling feature.
Specific embodiment
The present invention is described in detail With reference to embodiment.
Mining overburden STOCHASTIC DIFFUSION mechanism: the excavation of underground engineering has broken the equilibrium state that formation crude has, this to open
The tension that putting the excavation of formula will lead in protolith expands outwardly, and then causes the original order field in stratum to change, and think
Mining overburden diffusion process traverses five kinds of order fields such as stabilization-out-of-sequence-unstability-new stabilization of cause sequence-, difference locating for mining overburden
When order field, attractor it is different.The rock mass of non-excavation disturbance is in stationary field state, in such state, influences non-
The various factors of linear system are by intercoupling, in metastable state, after by outer force-disturbance, and entering momentum,
Coupling changes, and various factor responses are different, fluctuation occurs, system output is in change sequence field state, the order field
Rock mass external manifestation is to deform, and the characterization phenomenon such as crack diffusion, inherence shows as stresses re-distribution, and system order changes；
When the further fluctuation of impact factor in nonlinear system, and when mutually restricting, there is chaos effect, this state is out-of-sequence shape
State shows that part occurs damaging or be broken；If certain factor is in sequence ginseng state, system is further development of unstability
State, i.e., by local failure to overall collapse；After system overall collapse, balance promotes in the evolutionary process again of each factor
System is converted from nonuniformity to consistency, and system, which is in, at this time causes sequence field, i.e., towards Methodistic system converting state,
When reaching opposite order state, new stationary field is formed.
Technical solution of the present invention is as follows: (1) occurrence of structuring rock discontinuum, mark length, size, spacing, density, opening
The random distribution characteristic and Fractal Dimension of the conditions such as degree, filler, waviness, roughness, alteration extent, Spatial Coupling feature,
Establish rock mass parameter random statistical distribution model；(2) from structuring rock mass random distribution rule and stochastic parameter statistical distribution mould
Type is started with, based on random process and statistical theory, Cosserat MEDIUM THEORY, rock mass mechanics, thermodynamic argument, non-linear stochastic
Dynamic and control is theoretical, studies random parameter Evolution States in mining overburden random dynamic response diffusion process, and foundation is adopted
Overlying strata random dynamic response method of diffusion.
Advantage of the present invention also resides in:
(1) five evolutions and various field sequence attractor transformation mechanisms before and after mining overburden is adopted are proposed；
(2) non-linear stochastic dynamic and control theory mining overburden random field temporal-spatial evolution basic theory is introduced into grind
Study carefully, STOCHASTIC DIFFUSION method after studying big regional structure rock mass random distribution and being disturbed seeks mining overburden random field
Motion profile discloses mining overburden Stochastic Dynamic evolutionary process.
The above is only not to make limit in any form to the present invention to better embodiment of the invention
System, any simple modification that embodiment of above is made according to the technical essence of the invention, equivalent variations and modification,
Belong in the range of technical solution of the present invention.
