突出煤层瓦斯治理采区巷道优化设计

Optimal design of roadway in outburst coal seam gas treatment area

突出煤层瓦斯治理采区巷道的布置方式对于实现煤矿安全生产具有重要的意义,在考虑突出煤层巷道布置方式影响因素的基础上,充分考虑了突出煤层巷道工期、工程量、运输保障和维护等影响因素,从而结合井下工况及采区的地质情况,合理规划了采区准备系统,实现快速投产,增加巷道布置的灵活性。合理优化采区设计,突出煤层采用"一区五准""一面五巷"的巷道布置方式,在给瓦斯治理工程提供保障的同时,合理优化了煤层采掘的生产系统。

Coal gas control of mining roadway arrangement for coal mine safety in production is of great importance,considering the prominent factors affecting coal seam roadway arrangement,on the basis of fully considering the time limit for a project of coal drift,quantity,transportation,security and influence factors such as maintenance,according to downhole conditions and geological conditions of mining area,the reasonable planning of the first mining system,achieve rapid production,increase the flexibility of the roadway layout.The design of mining area is optimized rationally,and the roadway layout of“one area and five areas”and“one side and five lanes”are adopted to highlight the coal seam.The production system of coal seam mining is optimized rationally while providing guarantee for the gas control project.
