Aiming at the safety and inefficiency issues existing in the mining of Mianhuakeng mine, this study established a three-dimensional geological model of the ore body and conducted research such as stope structure parameter simulation and numerical simulation of deep-hole blasting disturbance, then obtained stope structure parameters and mining process parameters. Through on-site mining tests to verify and optimize these parameters, a pillarless sublevel deep-hole continuous mining technology was developed. This technology enables simultaneous operation of multiple processes and unmanned operation in the stope, resulting in the monthly production capacity of the stope approximately three times that of the existing horizontal slicing backfill mining technology, and a reduction in the direct mining cost of about 13%, significantly improving the mining efficiency and safety of Mianhuakeng mine.

针对棉花坑矿井开采中存在的安全性差、效率低等问题，通过建立矿体三维地质模型，开展采场结构参数模拟和深孔爆破扰动数值模拟等研究，获取了采场结构参数和采矿工艺参数，并通过现场采矿试验对参数进行验证和优化，最终形成了无间柱分段深孔连续采矿工艺，该工艺实现了多工序同时作业和采场无人化作业，使得采场月生产能力较现有的水平分层充填采矿工艺提高约3倍，采矿直接成本降低约13%，显著提高了棉花坑矿井的采矿效率和采矿安全性。
