Abstract: In order to solve the problems of static fracturing and penetration enhancement technology, such as short time and low pressure, this paper uses SPSS mathematical statistics to design orthogonal tests to optimize the optimal ratio of static fracturing agent raw materials, and conducts fracturing experiments based on the ratio on the coal samples with different pore laying modes; it also uses acoustic emission to quantitatively analyze the development of the fissures of the specimens during the fracturing process and predicts the time nodes of their fragmentation. The results show that: ①the optimal ratio of static fracturing agent is: expansion agent∶reinforcement agent∶water reducer∶retarder∶cement = 75∶8∶2∶6∶9, expansion agent and reinforcement agent have a significant effect on the static fracturing effect, and the other three components have a smaller effect on the static fracturing effect; ②the fracturing effect of double-hole fracturing and expansion pressure superposition is significantly enhanced compared with that of single-hole, the fracturing time of the specimens with guided holes is early and the specimens are broken more thoroughly, and the microfractures are well developed, and the reasonable distribution of holes can significantly improve the penetration effect of the static fracturing agent on the coal body; ③the acoustic emission ring counts and energies of the specimen of the coal samples are increased sequentially in the stage of compaction, elastic deformation and accelerated destruction, with a lower increase in the ring counts, and a relatively significant increase in the energy surge. The acoustic emission b-value shows a trend of increasing and then decreasing during the whole fracturing process, and decreases sharply before the destabilization of the specimen, which can be used as a precursor information point for the destabilization of the specimen. This study can provide theoretical support for the utilization of static fracturing agents in mines with high gas and low permeability coal seams.
