矿井安全监控系统的管理

煤矿安全是近年来国家安全管理工作的重中之重,也是我国建立和谐社会必须要解决的问题之一.对此,国家投入了大量的人力物力来进行研究和科技攻关,以期能够对事故的发生机理和认识有所突破,从而能够有效地控制事故.其中,强调对矿井瓦斯等危险有害因素进行实时监控,及时发现其变化及其趋势,从而可以预先判断事故发生的可能性,达到提前预测事故、控制事故发生的目的.而国务院安全生产委员会也于2003年7月4日下发的《煤矿安全生产基本条件》第十条中规定:"高瓦斯、煤与瓦斯突出矿井应有瓦斯抽放措施,并装备安全监控系统",这也充分体现了国家在矿山安全管理方面对安全监控系统的重视.     

Carbon emission efficiency of thermal power in different regions of China and spatial correlations

In China, the power industry contributes significantly to carbon emissions, reducing carbon emissions in this industry is conducive to China's adaptation and mitigation of climate change. Researches on green and low-carbon power have attracted increasing attention. In this paper, we analyze and compare the carbon emissions from thermal power sector in 30 Chinese provinces, divided into three main regions. Based on the panel data over the period 2002–2016, we use a slacks-based measurement (SBM) model to measure the carbon emission efficiency of China’s power sector. The results show that the carbon emission efficiency of the system is relatively low, with marked differences among regions. Based on the Moran’s I, we further found spatial heterogeneity in carbon emission efficiency of provincial power sector. Policies for adaptation and mitigation of climate change should have regional differences. Interregional collaboration also plays a key role in adapting to and mitigating climate change. For China, it is an important issue to develop clean coal-fired power generation and vigorously develop renewable energy. From a global perspective, energy transformation needs to be continuously promoted. Promoting low-carbon transformation of global energy system requires deep technical cooperation and synergy. Global mitigation strategy should focus on the orientation of structural reform and constantly optimize the energy structure.
