The Use of Cryogenic Air in Supplied Air Respiratory Protection

The Mine Improvement and New Emergency Response (MINER) Act of 2006 implemented new regulations in the underground coal mining industry that allow for the certification of non-compressed gas equipment for respiratory protection in underground coal mines. NASA’s Kennedy Space Center (KSC) Biomedical Research and Engineering Laboratory (BRL) is investigating the potential to expand cryogenic air supply systems into the mining and general industries. These investigations have, so far, resulted in four separate comparison and hardware development programs. The Propellant Handlers Ensemble (PHE) and Level “A” Ensemble Comparison (LAE): This study compared worker thermal stress while using the industry standard Level A hazardous material handling ensemble as opposed to using the similarly protective Propellant Handler’s Ensemble (PHE) that utilizes a cryogenic air supply pack, known as an Environmental Control Unit (ECU) as opposed to the compressed air Self Contained Breathing Apparatus (SCBA) used in the LAE. The research found that, in a 102°F environment, test subjects experienced significantly decreased body temperature increases, significantly decreased heart rate increases, and decreased sweat loss while performing a standard work routine while using the PHE, compared to the same test subjects performing the same routine while using the LAE. The Cryogenic Refuge Alternative Supply System (CryoRASS) project: The MINER Act of 2006 requires the operators of underground coal mines to provide refuge alternatives that can provide a safe atmosphere for workers for up to 96 hours in the event of a mine emergency. The CryoRASS project retrofitted an existing refuge chamber with a liquid air supply instead of the standard compressed air supply system and performed a 96 hour test. The CryoRASS system demonstrated that it provided a larger air supply in a significantly smaller footprint area, provided humidity and temperature control, and maintained acceptable oxygen and carbon dioxide levels in the chamber for the required amount of time. SCBA and Mine Rescue System (CryoBA/CryoASFS) Another requirement of the MINER Act is that additional emergency breathing equipment must be staged along evacuation routes to supplement the Self Contained/Self Rescue (SCSR) devices that are now required. The BRL has developed an SCBA known as the Cryogenic Breathing Apparatus (CryoBA), that has the ability to provide 2 hours of breathing air, a refill capability, and some cooling for the user. Cryogenic Air Storage and Filling Stations (CryoASFS) would be positioned in critical areas to extend evacuation time. The CryoASFS stations have a significantly smaller footprint and larger air storage capacity to similar compressed air systems. The CryoBA pack is currently undergoing NIOSH certification testing. Technical challenges associated with liquid breathing air systems: Research done by the BRL has also addressed three major technical challenges involved with the widespread use of liquid breathing air. The BRL developed a storage Dewar fitted with a Cryorefrigerator that has stored liquid air for four months with no appreciable oxygen enrichment due to differential evaporation. Testing of liquid breathing air was material and time intensive. A BRL contract developed a system that only required 1 liter of air and five minutes of time compared to the 10 liters of air and 75 minutes of time required by the old method. The BRL also developed a simple and cost effective method of manufacturing liquid air that joins a liquid oxygen tanker with a liquid nitrogen tanker through an orifice controlled “Y” fitting, mixing the two components, and depositing the mixed breathing air in a separate tanker.

井下救援机器人控制系统的仿真与实现

本论文以新松公司和山东省科学院的《井下探测救援机器人的研究》项目为依托，展开井下探测救援机器人控制系统的研究。 我国的煤炭资源十分丰富，是世界上最大的煤炭生产国和消费国。我国煤矿大多数为矿工开采，不安全因素很多，矿井自然条件差，加上技术和管理等诸多方面不到位，使得我国煤矿矿井灾害事故频繁发生，人员伤亡十分惨重，煤矿安全形势已经十分严峻。 传统的救援方法只能通过提升绞车、移动式风车等设备清除垃圾，向井下通风，然后再搜救遇险矿工。这种方式危险性大，伤亡人数多，救援周期长，效率低。因此，迫切需要研发替代或部分替代救险队员进入矿井灾害现场进行环境探测和完成搜救任务的煤矿救援机器人，这对煤矿安全生产，建立特种危险环境下的工业救援体系具有十分重要的意义。 本文以沈阳新松公司的井下救援机器人为研究对象，对移动机器人控制体系结构进行了研究。主要工作如下： 从分析当前的体系结构入手，针对井下救援机器人的具体特点和设计要求，设计了一种以混合式体系结构为基础的移动机器人分布式体控制器。这种结构使用一种基于服务的概念，各个服务提供相当的功能，任意组合服务可以获得相应功能的机器人控制器。服务内部基于纵向的层次划分和横向的功能划分，并融合了特定的反应式行为。 本系统的特点是：自主与监控相结合，动作与感知相结合的行为，采用分布式程序的开发方法并且具有相当程度的开放性。在微软的机器人开发仿真平台上对该体系进行了实验仿真，并在新松公司井下救援机器人开发中实现了该系统。
