Abstract

The implementation of roof pressure-relief systems has been imperative for ensuring the safety of mining operations in deep rockburst mines. However, the integration of impact risk analysis and pressure-relief effect evaluation of overlying strata remains a significant challenge. Drawing upon the research background of large energy events and strong impact threat in the Xinjulong coal mine, this study proposes a novel methodology for quantifying impact risk and evaluating pressure-relief effects. The proposed approach integrates the empowerment and vulnerability index method, offering a novel and comprehensive approach to risk assessment. The specific conclusions of the study are as follows: The blasting pressure relief work has a “buffer energy release effect” on the impact load generated by the migration of thick-hard roof. The upper pressure is transferred to the goaf, and the energy field of the working face and the roof remains stable. The outcomes of the ISM model are consistent with the internal fracture mechanism of the roof rock mass, which encompasses generation, transmission and transformation of energy throughout the entire monitoring process of “energy−stress−displacement−working resistance−drilling cuttings”. The weight of microseismic monitoring (energy, frequency and spatial aggregation characteristics) accounts for 52.2%, and the source of impact risk remains the primary focus of evaluation. The vulnerability index method predicts two potential places with strong bursting liability in stage Ⅱ, carries out enhanced-hole blasting and coal seam drilling operations, which effectively prevents further expansion of damage area and damage range. This method represents a novel approach to the application of multi-dimensional data fusion in pressure-relief engineering, and offers significant guidance for the analysis of rockburst disasters and pressure-relief evaluation.

期刊介绍: Tunnelling and Underground Space Technology is an international journal which publishes authoritative articles encompassing the development of innovative uses of underground space and the results of high quality research into improved, more cost-effective techniques for the planning, geo-investigation, design, construction, operation and maintenance of underground and earth-sheltered structures. The journal provides an effective vehicle for the improved worldwide exchange of information on developments in underground technology - and the experience gained from its use - and is strongly committed to publishing papers on the interdisciplinary aspects of creating, planning, and regulating underground space.
