通风是矿井煤炭正常回采的基础,本文在综合比对压差计法、气压计法基础上,依据矿井实际需要,提出采用气压计法对山西某矿通风系统通风阻力进行测定,并对通风阻力分布情况进行分析。现场测定发现,矿井通风系统进风段、用风段、回风段分... 通风是矿井煤炭正常回采的基础,本文在综合比对压差计法、气压计法基础上,依据矿井实际需要,提出采用气压计法对山西某矿通风系统通风阻力进行测定,并对通风阻力分布情况进行分析。现场测定发现,矿井通风系统进风段、用风段、回风段分阻占比分别为15%、67%、18%,矿井现阶段通风处于容易通风阶段。并根据通风阻力测定结果,提出针对性通风优化措施建议。研究成果可为其他矿井通风阻力测定及分析提供经验参考。 展开更多

The HINT project is a four-country collective of Global heritage interpretation. HINT is a two-year project part funded Geoparks researching the uses and benefits of new technologies in by the European Leader Programme. The partners are Geopark Shetland (Scotland), Chablais Geopark (France), North Pennines Area of Outstanding Natural Beauty (England) and Geopark de Hondsrug (The Netherlands). Each partner has developed a pilot project to investigate the practicalities of interpreting and communicating heritage, especially geological heritage, using a particular technology. An overview of each of the four pilot projects is given. The overall aim of the pilot projects is to develop best practice in using new technologies for heritage interpretation and to share information and ideas within the project partnership and with geoparks and heritage organizations around the world. This paper, developed by the HINT partners, aims to give an insight into the practical process of developing interpretive tools using new technologies. Some common problems are highlighted and some ways in which these can be addressed are shown. 展开更多
