In order to achieve the detection of the mine working environment ,the design is proposed for mine environmental monitoring based on C # and OPC technologies. The design using the SIMATIC NET OPC as a server, making S7-400H and SIMATIC NET OPC server connection configuration, using the advanced programming language C# to achieve the operation of data read and write of OPC client with OPC Server,thereby realizes the purpose of data monitoring, data storage and warning handling on the host computer.%为了实现对矿井工作环境的检测，基于C#和OPC技术提出了一种对矿井环境进行检测的一种设计方案。该设计以SIMATICNETOPC作为服务器，对S7—400H与OPCSERVER进行连接配置，采用高级编程语言C#编程使OPC客户程序与OPCSERVER进行数据读写操作，从而在上位机上达到数据监测、数据存储及预警处理的目的。
