Igneous Rock Occurrence Prediction Based on Seismic Information Inversion and Its Influence Analysis During Coal Mining: A Case Study in Huaibei Coalfield
Source abstract
Abstract
Overlying hard and thick igneous rocks pose numerous potential safety hazards during the exploitation of coal resources. Identifying the spatial distribution of igneous rocks and analyzing their impact on coal mining are a primary research concern. In this study, a coal mine was investigated in depth. Initially, based on the seismic information, the authors predicted the occurrence conditions of igneous rocks in coal measure strata. Subsequently, two models were developed via the UDEC software4.00: one with igneous layers and the other without. Using the simulation results, the change law of stress, the roof abscission layer, and roof strata subsidence in the overburden during coal face advancement were analyzed. Through a comparison of the simulation results, the hazard-causing mechanism of the igneous intrusion was discussed. Consequently, the occurrence of igneous rocks in the overburden is crucial for predicting potential safety hazards, and the seismic inversion method can be considered an effective tool for evaluating overlying igneous strata.
