矿井工

But the air flow that coal mine need and characteristic curve of resistance of coal mine is alterable.

轴流式风机的实际工况，取决于风机的特性曲线和矿井的阻力特性曲线。

Therefore, we apply the distributed monitor and control network technology based on OMRON PLC to the mine hoist"s back-up protection control system, working-condition monitor system, analog data acquisition data processing system. And applying the HOST Link and the PLC Link communication technology, we realize the following functions, the real-time monitor and control the hoist"s running state and running speed on line, real-time dynamic display, unified management by computer.

为此我们把所研究的由OMRON公司的PLC组成的集散测控网络技术，实际应用到矿井提升机的后备保护控制系统和提升机的工况检测、模拟量的数据采集与处理系统之中，并且应用PLC网络中的HOST Link和PLC Link通信技术，具体实现了对提升容器的运行状态、运行速度的在线实时监控和动态显示以及计算机的统一管理。

China's coal production and the exploitation of workers in well-oriented, while the underground work is first of all faced the problem of ventilation in the mine production process, we must continue to be ground fresh air supply to the various underground sites for staff and the exclusion of breath, and diluted Underground a variety of toxic and harmful gases and mineral dust, mine to create a good environment to protect the underground staff's health and labor safety.

我国煤炭生产以井工开采为主，而地下作业首先面临的是通风问题，在矿井生产过程中，必须源源不断地将地面新鲜空气输送到井下各个作业地点，以供人员呼吸并稀释和排除井下各种有毒有害气体和矿尘，创造良好的矿内环境，保障井下工作人员的身体健康和劳动安全。

He is the most remarkable man that I have ever known.

他是我知道的人中最值得注意的人。

Increased appearance of lymphocele was noticed in patients with diabetic nephropathy, congenital malformations of the urinary tract, and inflammatory diseases, including glomerulopathy and extraglomerular ones, after high-voltage radiotherapy and after removal of the renal graft.

经过高压放射疗法和切除移植肾后，在糖尿病肾病患者、泌尿系统先天性畸形患者和炎症患者身上发现淋巴囊肿有所增加，包括肾小球病和球外疾病等。
