为改善潘一矿1241(3)工作面的支护情况,首先采用岩层质量指数法计算出煤层上方各岩层的岩层质量指数,用专家系统法算出直接顶和老顶的厚度,并算出直接顶和老顶的各个运动参数,然后详细介绍了位态方程,用位态方程求出不同阶段的支护强度,取其中最大值作为液压支架的支护强度,接着用算得的最大支护强度求得支架工作阻力,最后设计出工作面的液压支架。
In order to improve the support of 1241 (3) working face of Panyi Mine, the rock mass quality index of each rock formation above the coal seam is first calculated by using the rock mass quality index method. The thickness of the direct roof and the old roof is calculated by the expert system method, And the top of the various motion parameters, and then introduced the equation of position, using the equation of state to find the different stages of support strength, whichever is the maximum as the hydraulic support strength, and then calculated with the maximum support strength The work of the stent resistance, the final design of hydraulic support face.
