综放开采的矿压控制实践

Practice controlling underground pressure in fully mechanized mining withtop coal caving, Dongtan Colliery

在大量现场实测及矿压控制实践的基础上，系统总结了东滩矿综放开采的岩层活动规律及矿压显现特点，并对不同架型的适应性进行了评价，为该矿综放支架的选型设计和改造提供了依据。

Abstract Based on a lot of field observation data and controlling practice ofground pressure in Dongtan Colliery, the paper summarizes systematically thestratum activities and the characteristics of the phenomena of the groundpressure caused by fully-mechanized mining with top-coal caving. Then itputs forward an assessment on the adaptability of different supports. Thiswork provides with a basis for the selection and reform of hydraulic supportsuitable for the top-coal caving of the Colliery.
