Research on optimizing structure parameters in Taoxikeng Tungsten Mine
摘要
Abstract
It is extremely important to make a reasonable selection of the structure parameters of the stope to meet high efficiency and ensure the safety of mine production. Taoxikeng Tungsten Mine is an important mining area of Zhangyuan Tungsten Industry Co., Ltd. With the shallow hole mining method adopted, the recovery process doesn't have good applicability, causing cracks in the tunnel roof and damage to the mining hopper, which had a negative impact on the operation of the mine. Here, the structure parameters of the stope needed to be selected again. Nine groups of mining plans were designed when the 256 mid-section and 206 mid-section of Fenglingkeng Mine area were taken as the research object, and the span of mine house, thickness of columns and top columns as variables accordint to the actual production conditions. ANSYS was used to build a model and imported FLAC3Dto perform numerical simulation. When the calculation results of each plan to make comparisons and analyses combined, the optimal structure parameters of the stope were determined.关键词
