Accurate predictions of the coal temperature in spontaneous combustion (CSC) are important for ensuring mine safety. Gas (the Zhaolou Shandong Province, China) was used this paper. A large CSC experimental device adopted to obtain its characteristic temperatures from macroscopic characteristics gas production. simulated annealing-support vector machine (SA-SVM) prediction model proposed reflect complex nonlinear mapping between gases and temperature. The risk degree estimated time domain,...
A thermal analysis experiment was conducted in O2/N2/CO2 and O2/N2 atmospheres (O2 concentrations were 21, 14, 8, CO2 0, 39, 46, 52) to investigate the behavior of coal oxidation combustion. Results demonstrated that an elevated concentration or decreased O2 had a delaying effect on thermogravimetric differential scanning calorimetry (DSC) curves; moreover, characteristic temperatures substantially augmented. When 21 vol%, total heat released by coals (highly volatile bituminous coal) B...
A novel and versatile route for fabricating flame‐retardant microcapsules via microfluidics technology is reported. The were prepared with a dimethyl methylphosphonate (DMMP) core an ultraviolet‐curable (UV‐curable) polysiloxane shell. Furthermore, UV‐curable was synthesized. synthesis mechanism of the curing analyzed. To verify that DMMP encapsulated in microcapsules, X‐ray fluorescence used before after microencapsulation. resulting well monodispersed exhibited good spherical shape smooth...
Airtight walls are vital to prevent spontaneous combustion of residual coal as caused by air leakage. A new type foamed concrete (FC) was developed control FC specimens four densities (250, 450, 650, and 850 kg/m 3 ) were prepared for use in a series physical mechanical tests. thickener used the shrinkage collapse. The permeability decreased approximately exponentially with an increasing density. On contrary, compressive strength ( σ elastic modulus E increased exponential linear...
ABSTRACT Environmentally friendly, flame‐retardant, and relatively low‐density (0.25–0.31 g cm −3 ) silicone foams (SiFs) were successfully obtained through dehydrogenation at room temperature (RT = 25.0 °C). Moreover, a flame‐retardant system for SiFs was synergistic combination of platinum (Pt) compounds, superfine aluminum hydroxide (ATH), ultrafine calcium carbonate (CC). The smoke suppression, flame retardance, mechanical properties, thermal stability with Pt ATH, CC tested using the...
Implementing a sealing measure on both ends of the mine tunnel fire is an important approach for extinguishing. In order to explore effect different velocities temperature distribution during dynamic sealing, series full-scale models were built using Pyrosim, and Fire Dynamics Simulator (FDS) was carried out investigate smoke beneath ceiling in symmetrical ends. The results show method led substantial increasement when HRR relatively small (2 MW). And with acceleration velocity, time reach...
Low-density, flame-retardant silicone foams (SiFs) were obtained through appropriately blending super fine talc powder (SFT) and hollow glass beads (HGB). The effects of SFT HGB on mechanical properties, flame retardancy, thermal stability SiFs investigated. incorporation significantly improved the properties SiFs, showed a positive effect reducing density SiFs. retardancy could be prominently by interfusing HGB. achieve UL-94-V0 rating with no less than 10 wt% or 5 Remarkably, peak heat...
