目前我矿副井提升绞车任务繁重:它既承担频繁的提矸、下料、下火药的任务,又承担不定时的升降人员的任务。由于信号工误发信号或绞车司机感知错误,往往造成错误或错向开车,如井下信号工未发信号,而井口信号工已向绞车司机发出开车信号,或井口信号工根本未发开车信号,绞车司机就启动绞车等情况,在矿井提升事故中占有很大比例。事故发生后,由于不能拿出可靠的 At present, mine auxiliary shaft hoist heavy lifting tasks: it not only undertake frequent mention refuse, unloading, the next gunpowder tasks, but also assume the task of lifting personnel from time to time. As the signal error signal or winch driver perception error, often resulting in errors or wrong driving, such as underground signal workers did not send a signal, and the wellhead signal driver has issued a driving signal to the winch driver, or wellhead signal operator did not send a car signal, The winch driver started the winch and so on, occupying a large proportion in the mine ascending accident. After the accident, can not come up with reliable
