用非线性规划法确定主要开拓巷道的断面几何参数

Geometric Parameters of the Main Roadway Sections Determined by Nonlinear Programming

①作为井下主要开拓巷道的阶段运输大巷、回风大巷等，服务年限长，建设投资大，其断面几何参数的确定，直接影响着矿井的经济效益，本文把与巷道断面几何参数有关的掘进费、维护费、通风电力费以及三种费用的利息费相加，建立目标函数Ｗ＝ｆ（Ｂ）（又称综合费用函数）讨论在满足约束条件（１）Ｂ＿Ｘ≤Ｂ≤Ｂ＿Ｄ（２）Ｓ≤Ｓ＿Ｄ（３）Ｖ≤Ｖ＿Ｇ的情况下，求能使综合费用Ｗ最小的断面净跨Ｂ＿Ｊ（称经济净跨）和净高Ｈ＿Ｊ（经济净高）。

The section geometric parameters affect the economic benefits of the mine directly because the service life is long and the construction investinent is huge for the level service roadways and main ventilating ways of the main development roadway,The paper established a objective function,W=f(B) (synthetical cost function),according to the factors related to the geometric parameters of the roaway section,such as driving cost,maintenance cost,vantilating power cost and their interests.In order to gain both Clear section span B_J(economic clear span )and clearance beight H_J(economic clearance height) which make synthetical cost mininum the paper discussed the objective function in following constranint conditons:1B_x≤B≤B_D 2 S≤S_D 3 V≤V_g
