摘　　要：为了找到矿井承压水上带压开采的有效方法,对峰峰矿务局四矿4804(4904)、4806(4906)两个近距离煤层协调开采工作面的底板岩体移动规律进行观测研究,研究表明:近距离煤层采用上下工作面协调开采的方法,并加快工作面推进速度,能有效地控制矿山压力、减轻工作面的采动影响程度,从而最大限度地减小了煤层底板破坏深度,也就相对增加了底板隔水层的厚度,减少了煤层底板突水的几率,从而达到安全开采的目的。因而近距离煤层协调开采是承压水上带压开采防止煤层底板突水的有效采煤方法。In order to find an effective method of mine confined water mining with pressure, No. 4 Mine of Fengfeng Mining Bureau, 4804 （4904）, 4806 （4906） two close coordination of coal seam mining working face floor rock mass movement observational regularity was studied. Research showed that close distance coal seam using the method of upper and lower face coordinating mining, speeded up the working face advancing, mine pressure can be controlled, lightened the working face in mining influence degree, minimized the coal floor damage depth, relatively increased the thickness of bottom water-resisting layer, reduced the coal floor water inrush risk, achieved the goal of safe mining. Thus close coordination of coal seam mining confined water from coal floor was the effective prevention of mining coal mining method under pressure.
