摘　　要：利用最优微积分逼近法来测定西北地区不同层重叠煤炭的压力;对西北地区不同层重叠煤炭的压力进行测定分析是精确开发不同层重叠煤炭资源的基础;传统不同层重叠煤炭压力测定方法采用连续预测的方法,采用内插值的方法实现测试,无法精确反应系统的压力变化特性;提出利用最优微积分逼近法的不同层重叠煤炭压力测定,首先对不同层重叠煤炭的压力数据进行采集,然后对采集来的数据进行微积分理论预测处理,以最优逼近函数为目的,逐步迭代运算,最终实现最优化的不同层重叠煤炭多层压力特性;最后采用一组实际不同层重叠煤炭进行测试,结果显示,采用最优微积分逼近法的对西北地区不同层重叠煤炭压力测定时,煤炭精细压力分布特性被很好的显示出来,具有很好的工程应用价值。Using the optimal approximation method to determine the pressure different calculusoverlapping coal in northwest area of Northwest China;pressure determination of different layers ofoverlapping coal analysis is the basis for precise development of different overlapping layers of coalresources;using the method of continuous prediction method for the determination of different layers ofoverlapping traditional coal pressure,by using the method of interpolation test,pressure characteristiccan not accurately reflect the system;put forward the optimal approximation method for different layersof overlapping calculus coal pressure measurement and the first to collect pressure data of differentoverlapping layers of coal,and the collected data were calculus theory prediction,approximation functionfor the purpose of optimal iterative operation,finally realize the optimization of different layers ofoverlapping coal layers the pressure characteristic;a group of actual different overlapping coal testingnode The results show that the distribution of fine coal pressure is well displayed by using the bestapproximation method,which is of great value in engineering application.
