The three-dimensional analysis of the influence of mining coal seams on the floor strata

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

In the coalfields of North China, coal seams lie in Permo-Carboniferous strata, which are underlain by Ordovician limestone. In general, the limestone aquifers contain an abundant supply of water and are confined. The activities of mining these coal seams are threatened with karst water from the Ordovician limestone. This paper presents a novel mechanical model by simplifying the additional vertical stresses on coal pillars around the working face. The numerical method based on the multilayered fundamental solution is applied for the calculation of three-dimensional displacement and stress fields induced by mining coal seams. This study supplies the understandings of floor strata in mining coal seams.
