综采工作面斜长等长的控制方法

The Ways to Contort the Iinclined and Equivalent Length of Combined Coal Face

为克服传统综采工作面上下风巷平行布量时 ,因煤层倾角变化大而造成工作面倾斜长度不断变化给工作面回采带来的不利影响 ,通过对三维地震资料的分析 ,在顺槽掘进过程中运输顺槽按设计方位且超前轨道顺槽施工 ,并不断对两顺槽标高进行测量调整轨道顺槽的方位 ,使工作面斜长变化值控制在一定范围内 ;回采过程中不增减设备 ,实现综采工作面安全、高效的顺利回采。

When the up-down wind tunnel of the traditional combined coal face is measuring parallelly, the continual changes of the inclined length of the coal face which the uncertainty of tilting angle of coal seam alters, bring the harmful effects to the coal extraction Through the analysis of three-dimensional data, the paper introduces a way to control the change of the inclined length within the scope, so the coal extraction is finished safely and effectively safely and effectively, without increasing or decreasing equipment.
