因本人英语水平有限，所以请高手帮忙翻译论文摘要如下：摘要近年来，我国经济快速发展，煤炭需求总量逐渐增加，要求煤炭工业维持较高产出，是造成煤矿超能力开采的宏观直接原因，超能力开采已经成为全国煤炭工业增加产出的主要手段之一，也成为我国煤矿各种事故的重要导火索。

It was shown that coal seam floor failure depth of working face 2121 was 32.5 to 5 m, approximately three times as deep as that of shallow working face(in genera l,9.15 to 12.0 m). Coal seam floor failure depth increased with mining depth. Potential risk of water inrush through coal seam floor of working face 2121 is much higher for deep mining than for shallow mining.

试验结果表明：该工作面底板破坏深度为32.5~35 m，比300 m采深以内的工作面实测深度(9.15~ 12.0 m)增加2倍以上，说明随着开采深度的增加，煤层底板采动破坏深度呈明显增大的趋势，因此，在水压和破坏深度二者同时增加的条件下，2121工作面深部煤层开采的突水危险性远远大于浅部煤层。
