矿井交岔点平面尺寸计算,在不少设计资料中已有计算公式,但这些计算公式是假设交岔点的交角β大于或等于弯道转角γ,即β≥γ.在实际工作中也会遇到因巷道交角较小,而出现β<γ的情况,此时,原有的计算公式中有部分就不适用了.例加,笔者在旗山矿-700m水平改扩建工做西轨道大巷与胶带机运输巷的交岔点设计就遇到了这样的情况,在进行这种交岔点的设计中,笔者总结出了一套计算公式.
Calculation of the mine shaft cross-point plane size, in many design information has been calculated, but these calculations are based on the assumption that the intersection angle β is greater than or equal to the corner of the curve γ, that is, β ≥ γ In practice, will Encountered due to the smaller angle of the roadway, and the case of β <γ, at this time, some of the original formula does not apply.Examples plus, the author at the Qianshan mine -700m horizontal expansion project to do large orbit Alley and conveyor belt conveyor crossing intersection design encountered such a situation, in the design of this intersection point, I summed up a set of formulas.
