煤矿突水灾区变坡巷道堵塞特征
Congestion characteristics behind slope changing roadway in coal mine water inrush disaster area
摘要
Abstract
This paper is a response to the rapid rescuing the people trapped in disaster area following the occurrence of coal mine flooding.The study building on an insight into the impact on emergency rescue of the congestion occurring on slope changing roadway in coal mine water inrush disaster area consists of analyzing the physical and mechanical characteristics of congestion body seen on the slope changing roadway in the disaster areas;according to different medium,classifying the bodies into the three types:stone pile up,the coal deposition,hybrid coal and rock;identifying the way all types of sediments accumulate,developing physical and mathematical models for congestions occurring on slope changing roadway in the disaster area to analyze the precipitation accumulation characteristics and scope under the three conditions;and thereby deducing the function relationship between jam area edge tracing line and the angle,slope length and the fault size of slope changing roadway.The research may provide theoretical and technical support to an improved emergency rescue.关键词
