During coal and rock loading, a significantly large number of electromagnetic signals are generated as result fracture appearance crack expansion. The generation signal is the comprehensive embodiment failure behavior. Therefore, contain complex rich messages that can reflect damage process degree rock. In this work, multifractal theory applied to analyze nonlinear characteristics wave its spectrum induced during rock, which present good correlation with process. non-uniform, non-continuous...
Coal and rock dynamic disasters have been the main concern in underground engineering because these seriously threaten safety of miners industrial production. Aiming to improve EMR AE monitoring technology, refined nonlinear characteristics during coal splitting failure are studied using Hilbert-H multifractal theory, valuable information pertaining fracture law contained waveform was revealed. The results show that related process crack propagation. They possess same initiation time...
Abstract Efficient and accurate monitoring early warning of coal dynamic disaster other disasters can provide guarantee for the efficient operation mine transportation system. However, traditional threshold method often fails to some accidents. To address above issues, a new was proposed based on "quiet period" phenomenon AE EMR during fracture. It is found that, present before load reaches peak stress, which could be used as one precursors warn imminent failure rock specimens. MS signals...
The immune interactions occurring between parasitoids and their host insects, especially in Drosophila-wasp models, have long been the research focus of insect immunology parasitology. Parasitoid infestation Drosophila is counteracted by its multiple natural defense systems, which include cellular humoral immunity. Occurring hemocoel, responses involve proliferation, differentiation, migration spreading hemocytes parasitoid encapsulation them. Contrastingly, rely more heavily on melanization...
The stress and gas pressure in deep coal seams are very high, instability failure rapidly intensely occur. It is important to study the infrared precursor characteristics of gas-bearing failure. In this paper, a self-developed stress-gas coupling experimental system was used analyse radiation temperature (IRT) thermal image gas-free coal. changes areas anomalous regions effect on precursors were examined. results show that high-temperature arise mainly when fails under loading, whereas has...
The accurate detection of coal seam stress field effectively prevents and gas outbursts. This study uses wave velocity, velocity anomaly coefficient, gradient as indicators to identify anomalies in seam. results show that these three are all positively correlated with load, while changes the coefficient more gentle than those velocity. degree damage can be judged by transition between high low zones identified gradient. In areas affected geological structures such valleys mountain tops, may...
The characterization of micro-surface mechanical and electrical properties the natural rock materials remains inadequate, their macroscopic performance can be better comprehended by investigating surface properties. With this purpose, present research focuses on characterizing morphology, Derjaguin-Muller-Toporov (DMT) modulus, adhesion, potential granite, shale, limestone employing atomic force microscope (AFM) as a pioneer attempt. results show that morphology fluctuates within hundreds...
Abstract Accurate prediction of coal and gas outburst (CGO) hazards is paramount in disaster prevention control. This paper endeavors to overcome the constraints posed by traditional indexes when dealing with CGO incidents under low pressure conditions. In pursuit this objective, we have studied established a mechanical model working face abnormal stress excitation energy conditions CGO, proposed method for predicting risk stress. On site application verification shows that strong hazard...
