Abstract

The invention discloses a dynamic prediction method for multisource gas emission quantity of a fully mechanized caving face. The dynamic prediction method comprises the steps of confirming types of gas emission sources according to geology and exploitation conditions of the fully mechanized caving face; acquiring gas emission prediction reference data of the fully mechanized caving face; calculating mechanical mining coal gas emission quantity; calculating putting coal gas emission quantity; calculating goaf gas emission quantity; calculating coal wall gas emission quantity; and calculating caving face gas emission total quantity. The dynamic prediction method is aimed at a fully mechanized caving face exploitation technology, key dynamic parameters affecting gas emission are considered, and the gas emission condition of the fully mechanized caving face is reflected more really and comprehensively, so that all-source gas emission quantity acquired according to the dynamic prediction method is relatively accurate, limitation of a conventional fully mechanized caving face gas emission quantity is solved, prediction accuracy of gas emission quantity of the fully mechanized caving faceis improved.

Description

technical field [0001] The invention belongs to the field of mine gas prevention and control, and in particular relates to a dynamic prediction method for multi-source gas emission in a fully mechanized caving face. Background technique [0002] The prediction of gas emission is the basis of mine gas prevention and control work, and can provide a basis for the layout and design of gas control. At present, the gas emission prediction methods of working faces mainly include the source prediction method and the mine statistics method, but they are mainly aimed at the gas emission prediction of fully mechanized mining face, and the applicability of the gas emission prediction of fully mechanized caving face is not strong, and the current gas emission The prediction method is mainly based on static indicators such as coal-rock geology and gas parameters of the working face, and does not consider dynamic parameters such as coal mining speed and coal transportation time, so the acc...
