A new type of efficient and anti-extinguishing materials to inhibit coal spontaneous combustion is required because the current situation short activity cycle existing technology. Now, polyethylene glycol (PEG) was used as a water-absorbing monomer polymerize various substances prepare an AB-type mining thermosensitive hydrogel that obviously thermoresponsive. The hydrogel, which low-cost stable, can be stored for long time, it prepared by compounding B components. orthogonal experiments...
This study added graphene oxide into a cement-based plugging material to prevent spontaneous combustion of coal by efficiently the cracks in and rock mass. The novel was prepared based on cement, fly ash, (GO), other additives. In this paper, effect GO nanomaterials properties investigated analyzing physicochemical structure, surface morphology, mechanical strength composite. new composite showed better quality with dense decreased pore volume, which indicated that addition affected...
The wettability of room temperature ionic liquids (ILs) on coal structure was studied by measuring contact angle, water-retaining property, and FTIR spectra. eight ILs utilized were [EMIm][BF4], [EMIm][NTf2], [PMIm][BF4], [BMIm][BF4], [HOEtMIm][BF4], [HOEtMIm][NTf2], [P4,4,4,1][MeSO4] [P4,4,4,2][DEP]. angle results showed that compared with distilled water, the angles decreased, indicating good wetting effect. However, different effects. Among them, [HOEtMIm][NTf2] had best effect,...
This paper provides the concept of import dependence between countries, which is a relative quantity. In order to reveal evolutionary characteristics countries in energy trade and its influencing factors, firstly, based on network analysis method, this constructs model (EIDN) among regions along Belt Road (B&R countries). Crude oil natural gas are taken as empirical objects, evolution two kinds EIDNs analysed. The result showed that most B&R had small number crude partners. However,...
Aiming at the problems of conventional cement-based foam plugging and filling materials, such as large amount cement, low utilization rate solid waste, unclear bonding, mechanism, it was proposed that a kind preventing fire material named inorganic solidified prepared from industrial slag, water-based main raw materials. Based on fluidity, expansion ratio mechanical strength foam, determined S105 slag powder with high content 60%~65% optimal chemical activator 6%. The dry density about...
