The Study On Water Losing Mechanism In Mining Stratum

It is certainty that caused groundwater loss by mining, and the induced geologicalenvironment calamity involves a wide range, strong latent, large dynamic change ofcoverage, long endangering time character etc. It is seriously endangering living ofmining area people, stability of the society and development of national economicconstruction. There are important theoretical value and realistic meaning to carry outresearch work of mining stratum water resource loss mechanism.The main research contents are:1 Combining large number of instances, groundwater loss by mining to causecompanion geological environment calamity, and the text points out noticed studytendency of is mining stratum water seepage at present;2 Describe study current situation of mining stratum water resource loss, and analyzeequivalent continuous medium model, dispersed medium model, double medium modeland their advantage and shortage, and has programmed finite element procedure of theunified mix model;3 Introduced basic genetic algorithm principle and realize technology, and put forwardimproving measure, which can accelerate the speed of convergence of genetic algorithm,and I have programmed optimized procedure of genetic algorithm based on MATLABsoftware;4 Utilizing genetic algorithm, and combining numerical simulation of finite element, thetext has got one kind method of obtaining accurately infiltration coefficient of rockstratum in case of small amount of priori information;5 Utilize the 4th contents' method, we can determine functional relation betweenseepage coefficient and hole pressure during numerical calculating, and the text usedGEO- SLOPE software to simulate three states of water moving law: having two waterbarrier stratum, one water barrier broken and upper and lower water barrier broken inmining stratum.
