As a matter of fact, the roof pressure will vary noticeably along face line. Nevertheless, most of mining engineers take only the pressure at the middle of the coal face into consideration, and deem it as a rule of thumb. Probably this will lead astray, since the main roof over the coal face acts as a pillar-supported "plate" . During the course of the fracture of the "plate" , the resulted pressures appeared at the ends and the middle of the coal face are obviously different in nature.

众所周知,沿着工作面长度方向顶板压力是不尽相同的。长期来人们主要研究工作面中部的顶板压力,事实上工作面上方的老顶如同支承在煤柱上的“板”一样,而“板”的断裂对工作面中部及上、下部的顶板压力影响是不一样的。 本文研究了各种不同支承条件下老顶岩层的初次破断型式。根据模型试验及实测资料研究了老顶的断裂过程、条件以及断裂的型式。根据试验,老顶断裂的型式可以分为横X型、X型及竖X型破坏。 试验证明,只有老顶呈横X型破坏时,工作面中部可以采用“砌体梁”的理论研究矿山压力,而对其它情况则必需用“板”的破坏理论研究矿山压力。

-This paper is an introduction about a developement and application of a plastic filter plate for a press filter. The plate has such advantages as light in weight, long duration, saving in filter cloth, easy in assembling, operation and maintenance. The main specifications are as followings, dimensions 1.5×1.5m, weight of a plate 82 kg, working pressure≤10kg/cm~2, temperature -1℃ to +50℃. The plastic plate is a pressed modelling with a main material of modified polypropylene. The plastic plate can be applied to a XMZ 340(500)/1500 press filter.

Based on the statistics of first weighting span in some collieries and the study on the fracture behaviour of the "plate" model of main roof, it is obtained that the first weighting span of main roof can be expressed by ai = lm - wt , where lm is span criterion, which represents the beam stability of the main roof; and the boundary-length coefficient wi , represents the effect of face length and boundary conditions on first weighting span.

本文根据大量初次来压步距的统计和老顶“板”模型破断规律的研究,论述了老顶初次来压步距a_i的构成。它由反映其自身稳定性的步距准数l_m与反映工作面长度和开采边界影响的“边—长”系数W_i之积构成,即a_i=l_m·w_i。得出了工作面长度对老顶来压步距及其极限悬露面积的影响均呈w形曲线关系的结论。开采边界不同,其w形曲线也略有差异。据此,提出了常见的四种开采边界条件下来压步距的计算方法,以及利用实测步距推广到邻近工作面中去的换算方法。同时,对顶板分类提出应以步距准数l_m为指标,并用作w形曲线图法进行分类。
