针对不同煤层顶板条件及顶煤介质属性的变化,弄清综采放顶煤采场的顶板结构形式及支架围岩关系,这是科学进行采场支护设计、采取相应措施控制综放采场矿山压力、提高放顶煤开采效益的重要前提。本文主要阐述了安全高效综放采场矿山压力控制、顶煤运移和破坏规律等技术问题。
According to the roof conditions of different coal beds and the change of the properties of the top coal, it is necessary to understand the roof structure of the fully mechanized top coal caving mining area and the relationship between the supports and supports. This is the scientific design of stope support and the corresponding measures to control the fully mechanized caving face Mine pressure, improve the efficiency of caving coal mining an important prerequisite. This paper mainly elaborates the technical problems of mine pressure control, top coal transportation and destruction rules of safe and efficient fully mechanized caving mining face.
