Research of New Material Restraining Coal Spontaneous Combustion by the Way of Release Water Mist

In order to control the coal spontaneous combustion, a new material to restrain coal spontaneous combustion was researched in this paper. Through the platform of experimental was built, and the material was released by water mist, the characteristics of new material and water mist was used, and then researched the change concentration of O2, CO and CO2 in experimental platform under this new material, the change of temperature in different parts of burning space. As the same time, we contrast studied added material or not when the coal spontaneous combustion, the data and phenomenon were analyzed in experimental and the mechanism of restraining was put. This studies show that the material has good effect with restraining when adding this material by water mist to coal spontaneous combustion.

Fire Extinguishing

In China, as popularizing the technology of fully mechanized top-coal mining and increasing the strength and depth of mining, the gutter-up gob can be formed. But the work of fire preventing and extinguishing for its coal spontaneous combustion is more complexity and difficulty. In this paper, based on geology parameters and mining practice for 93up12 fully mechanized top-coal caving face in Nantun coalmine, the form and character of gutter-up gob are analyzed. According to the hidden danger of high temperature for spontaneous combustion in the gob, we adopt the comprehension technologies of fire extinguishing and preventing which include sealing air-leakage, grouting, and injecting compound gel with fly-ash, foam of retarding oxidation, liquid carbon dioxide, and gas of nitrogen. By putting in practice the pre-controlling technology in gutter-up gob and monitoring data of target gases, it obtains a good effect and ensures the safety in production of the fully-mechanized top-coal caving face.

The Way

Abstract This article finds its inspiration in the new interpretations of Gadamer’s hermeneutics, which underline the turn in his later period, and which focus on the conception of aesthetic experience as an experience of transcendence. The main thesis is that the understanding of artworks, as Gadamer describes them in contrast to the Kantian subjectification of aesthetics, can be paralleled with the way Orthodox biblical theology struggles to approach Holy Scripture in the context of Church and Tradition. The aim of this article is to bring new material to the growing reception of Gadamer among Orthodox scholars, and to initiate further discussion on the topic by showing the parallels and areas where this reception could continue.
