Abstract

This work aims to develop a method for determining the increase in stresses above an advancing longwall face of Western Donbas mines. The paper presents a solution to the problem. It is based on the analysis of geodetic instrumental observations of the earth's surface lowering and rock mass deformation above the advancing longwall face. Length and propagation in the roof and floor of the extracted seam are the main geometrical parameters of the zone of high rock pressure. Currently, the quantitative parameters of this zone are not considered. And its length under the conditions of Western Donbas is determined with an accuracy of 50%. Thus, research in this direction is relevant. The experimental basis for the research includes the results of observations performed at two vertical borehole extensometers and the results of data processing obtained at more than 30 observation stations on the Earth's surface. Thus, the research specified the geometrical parameters of the zone of high rock pressure and the nature of the vertical stress distribution within this zone. The paper introduces a method to determine a coefficient of stress increase above the advancing longwall face of Western Donbas mines. We also established the empirical coefficients of the vertical stress distribution function within the abutment pressure zone. There is a relationship between the lowering of the earth's surface and the values of the stress increase in the borehole edge part. The reliability of the obtained results is confirmed by geophysical studies in Western Donbas, as well as by the results of field observations.

这项工作的目的是开发一种方法来确定在西部顿巴斯矿井的一个推进长壁工作面的应力增加。本文提出了解决这一问题的方法。本文是在分析长壁推进工作面地表下沉和岩体变形的大地测量仪器观测资料的基础上提出的。抽采煤层顶底板的长度和扩展是高岩压带的主要几何参数。目前未考虑该区域的定量参数。在顿巴斯西部的条件下,其长度的确定精度为50%。因此,这个方向的研究是有意义的。本研究的实验基础包括两个垂直钻孔延伸仪的观测结果和地球表面30多个观测站的数据处理结果。从而明确了高岩压带的几何参数和高岩压带内垂直应力分布的性质。本文介绍了一种确定顿巴斯西部矿区超前长壁工作面应力增加系数的方法。建立了桥台压力区内竖向应力分布函数的经验系数。地表的下降与钻孔边缘部分的应力增加值有一定的关系。在顿巴斯西部进行的地球物理研究以及实地观察的结果证实了所得结果的可靠性。
