Material point method for simulating strong mining pressure manifestation in multiple hard roof panels controlled by hydraulic fracturing

Ground hydraulic fracturing has emerged as an effective technique for mitigating strong mining pressure manifestations in longwall top coal caving (LTCC). However, the influence of different hydraulic fracture types on the strength characteristics of hard roofs (HR) remains unclear, as does their im...
