近距离煤层群回采巷道支护优化模拟研究

摘要

Influenced by 2089 underside mining face and geological factors ,the mine pressure behaves violently in the process of tunneling 3093 duct ,which not only affects the production schedule ,but also increases the risk factors .In order to make the support design more scientific and pertinent , the author conducts a simulation study on support optimization according to the force analysis of the arch support of 3093 duct ,and makes an op‐timized analysis of roadway support parameters ,which can provide the basis for similar roadway design .%受2089下工作面和地质因素的共同影响，3093风道掘进中矿压显现剧烈，不仅影响了生产进度，也增大了危险系数。为了使支护设计更加具有科学性和针对性，对3093风道拱形支架进行了受力分析和支护优化模拟研究，并对巷道支护参数进行了优化，为同类巷道支护设计提供了依据。
