泸县张岩沟煤矿水土保持工程设计

当前由于工程建设或矿山开采造成的水土流失越来越严重，如何防治这类水土流失已引起有关部门的重视。本文以相关的水保工程设计规范和水力学、工程力学理论为基础，就泸县张岩沟煤矿开采所造成的水土流失问题提出水土保持的具体工程手段和设计方法。煤矸石挡渣坝设计经济、安全，可堆放弃渣量10．13万m^3以上，矿方可持续使用7．5年；渠系设计满足工程要求的20年一遇洪水标准。

Water and soil conservation engineering design for coal mine field of Zhangyangou in Luxian county

Recently water and soil loss caused by engineering construction or mine mountain exploitation is becoming more and more serious and widespread, How to take precaution and to treat this kind of water and soil loss have been taken into account by related departments. According to the engineering design regulations for water and soil protection, and the hydraulics and engineering mechanics theories, based on water and soil loss problem caused by coal mine exploitation of Zhangyangou in Luxian county, the paper brings forward the actual engineering methods and design methods. The designed blocking dam for coal mine gangue is economic and safe, which can stack more than 101 300 cube meters and can be used for 7.5 years continuously. The design for canal system meets the needs of the standard of every 20 years flood chance, The design principle and process can be used for similar conditions.
