The Floor Heave Mechanism and Control Technology of Gob-Side Entry Retaining of Soft Rock Floor

Sustainability, 2023
Extensive soft-rock floor heave in gob-side entry retaining considerably restricts the efficient and sustainable production of the mine. The mechanical capacities of roadway roof and floor strata are discussed through laboratory tests by taking the N2301
