双容器立井提升过卷高度的动态分析

Dynamic Analysis for Overwind Height of Double Casket about Shaft Hoisting

过卷高度取值过小,影响提升的安全性;过卷高度取值过大,增加井架高度,造成浪费。根据《煤矿安全规程》规定的安全制动力矩推导出计算制动减速度的计算方法,从而可以让设计人员方便计算出立井的过卷高度。

If overwind height is too small,the safety of hoisting should be influenced.If overwind height is too high,the height of frame about shaft would be much higher.Based on the brake torque of ＂Safety regulations in coal mine＂,a method of deceleration for brake is given in this paper.This method will be very easy for calculation of overwind height for designer.
