东荣三矿综采工作面矿压规律研究

结合双鸭山分公司东荣三矿的实际条件，从矿压显现的时空关系及其相互作用规律出发，采用现场测试及数值模拟的实验方法，研究近距离煤层群开采过程中产生的应力场及位移场对回采工作面及其周边巷道的影响；从而确定煤层群开采过程中，采准巷道与工作面开采之间合理的时空关系及其巷道的合理支护方式。

Study on Mine Pressure Regularity of Fully Mechanized Mining Face in Mine of Dongrong 3

Combined with the ShuangYashan Dongrong llI coal mine,the space-time relationships and interaction rule~; of the mine pressure, on-site observation and numerical simulation are adopted to study the stress field and displacement field generated in the plcess of the closeseam mining. Their impact on the backstopping mining face and the surrounding roadway is also discussed. Thus, the national space-time relationship and a reasonable supporting way of roadway between quasi-roadway and the mining face exploitation during coal seams mining are determined.
