摘要翻译成英文矿井下工作环境复杂，我们研究的价值在于可以及时检测出煤矿工人跌倒，睡着，被重物砸中后这几种危险的运动状态，

Mine under the complex work environment and the value of our research is to timely detect the mine workers fall, fall asleep, after the weight of this state of several kinds of dangerous sports, in order to reduce the happening of the tragedy. This team USES an acceleration sensor, acceleration monitoring system as the core of the coal mine workers' movement state monitoring device, using MEMS technology [8] to place it within the workers safety helmet and to detect the labor movement. The simulation experiments have been able to realize to fall, fall asleep, was the weight of the several kinds of dangerous motion detection.
