AI Technical Summary

Technical Problem

Existing technologies are insufficient for the effective coordinated prevention and control of water inrush and shock hazards in deep coal mining. Traditional methods are limited in scope and cannot achieve systematic management from the perspective of stress-fracture-seepage multi-field coupling.

Method used

A method for coordinating the prevention and control of mining-induced water inrush and shock disasters in coal mines is provided by roadside backfilling. By arranging composite roadside backfill bodies on one or both sides of the mining roadway, the backfill bodies have the functions of bearing support, seepage prevention and water isolation, and energy buffering. They improve the stress transmission path of the surrounding rock, block mining-induced fractures and structural water-conducting channels, and weaken the propagation of dynamic loads and the dynamic response of the surrounding rock.

Benefits of technology

It achieves synergistic suppression of water inrush and rockburst disasters, reduces local stress concentration and elastic energy accumulation, improves the overall stability and safety of the surrounding rock of the roadway, and significantly reduces the risk of water inrush and rockburst.

Abstract

本发明涉及煤矿安全开采技术领域,特别是涉及一种煤矿采动突水与冲击灾害协同防控巷旁充填方法,首先识别突水风险区、冲击危险区及耦合灾害区并确定充填范围,然后在回采巷道一侧或两侧布置具有承载支撑、防渗隔水及缓冲耗能功能的复合巷旁充填体,利用该充填体改善围岩应力传递路径、封堵导水通道并吸收冲击能量。本发明通过巷旁充填对围岩应力场与渗流场进行耦合调控,克服了传统技术分别治理的局限,实现突水与冲击灾害的协同抑制,能够有效降低冲击地压发生概率、显著减少突水风险,并削弱灾害链式反应,提高巷道围岩整体稳定性。本发明适用于深部煤矿复杂构造区突水与冲击地压耦合灾害的协同防控。
