Abstract


Goaf gas emission to account for a large proportion of the gas emission, only to understand and master the occurrence of air flow flow state and goaf gas migration and emission law to identify the gas accumulation only can the targeted adjustment stope ventilation system, determine the parameters of stope reasonable ventilation to prevent the accumulation of gas. However, due to the constraints of the site conditions, it is difficult to observe to adopt the Gas Flow physical process. This thesis from the perspective of the test, to 14205 Shaqu Mine mechanized mining face as the prototype build a simulation study of the stope goaf gas migration test in the laboratory system, based on the similarity theory and similarity criteria for the conduct of mining The goaf Merry flow state and gas migration law. Paper a more detailed analysis of the stope goaf gas emission law and emission; qualitative analysis for the the goaf gas concentration distribution law goaf; same time the use of the cross three districts, \the theory combined Shaqu Mine 14205 Face the specific circumstances, to determine the height of the caving zone and goaf a \The paper was established in order to ensure that a similar relationship between model and prototype, to achieve the purpose of science simulate real underground environment, goaf gas migration should follow similar guidelines in the three-dimensional model based on the similarity theory and similarity criteria, to determine the geometry of the model and the other relevant parameters, model and prototype geometrically similar movement similarity and dynamic similarity. Papers structural design and build three-dimensional models, the main contents include: the design model of the main ventilation systems, simulation test bench stope, fan blower attachment, collection and detection system; spherical valve as a damper in the model, a model more ventilation mode conversion and use; goaf characteristics analysis, based on the completion of the analysis results goaf filling; calculation of local resistance and friction, selected according to the maximum ventilation resistance fan; gas release system design model based on the goaf gas sources and emission law; measured parameter selection detection element; strictly follow the geometric similarity requirements, reasonable experimental material to build a roadway in the laboratory, the test requires face and three-dimensional model of the mined-out area. Finally, using the model of the \
