Abstract

The invention discloses a method for identification and disaster prevention of residual detachment layers, which comprises the following steps: according to the lithology of the overlying rock and its combination characteristics, and based on the principle of "composite beams", the positions of all detachment layers in the overburden rock are determined; Detachment; calculate the maximum detachment volume and maximum residual detachment volume of catastrophic detachment; determine the position of the maximum residual detachment; prevent and control residual detachment disasters. The beneficial effect of the present invention is to find all the separation layers in the overlying rock through calculation, to determine the disastrous separation layer, to determine the maximum residual separation layer amount, to determine the position of the residual separation layer, to realize the disaster prevention and control of the residual separation layer, and to reduce the The occurrence of disasters ensures the safety of coal mines. And the calculation parameters can be found in the coal mine technical data files, without adding additional workload; the calculation is convenient, and the on-site engineering and technical personnel can master it after a little training.

Description

technical field [0001] The invention relates to the field of coal mine disaster identification and prevention, in particular to a method for identification and disaster prevention of residual separation layers. Background technique [0002] In recent years, the "absorptive water" water disaster on the roof of coal mines has occurred frequently, causing shocking casualties and property losses. Huaibei Coalfield Haizi Coal Mine in 2005 "5.21" abscission water outburst accident caused a total of 5 deaths, the maximum water inrush 3887m 3 / h, and secondary disasters caused by rock burst; Zhuxianzhuang Coal Mine’s “1.30” abscission water disaster in 2015 caused a total of 7 deaths, with a maximum water inrush of 7200m 3 / h, the mining face is flooded. [0003] In the overlying strata of the coal seam roof, when the engineering geological properties of the thick and hard strata (commonly known as "key strata") and the underlying soft strata are quite different, under the influen...
