摘要：

针对金属矿采空区难治理问题，以地下空间利用为出发点，结合国家能源战略储备需求，提出以充填采矿为手段，在金属矿大型采空区构建充填储库，用于储备石油、天然气等能源。结合金属矿充填采矿法的特征，提出采矿-充填-建库（MBS）协同系统理念。依据采矿、充填、建库的工艺特点，构建了采矿-充填-建库协同系统结构体系，研究了该系统的协同特征，主要包括时间协同性、空间协同性、工艺协同性、环境协同性。明确了充填储库这一新型储库形式，按功能特征将充填储库分为充填储物库、充填储气库、充填石油储库3类；对充填储库尺寸和形状特征进行分析，将充填储库按形状分为方形、圆柱形、椭球形3类，并对其特点进行分析。以充填石油储库为例，研究了充填储库结构及高强-低渗功能充填材料特征，描述了充填储库群串并联结构特征，确定了充填石油储库工作原理；对充填储库稳定性进行分析，建立了充填矿柱安全距离判据，推导了充填储库顶板受力的计算模型。

Abstract:

Aiming at the difficulties in controlling the goaf of metal mine, based on the utilization of underground space and the demand of national energy strategic reserve, the backfill mining is proposed as a means to create the backfill storage of large goaf in metal mine, used for reserving oil, gas and other energy. In combination with the characteristics of backfill mining method, the concept of mining-backfill-storage building(MBS) synergetic system is put forward. Based on the process characteristics of mining, backfill and storage construction, the structure of MBS synergetic system is constructed; its synergetic characteristics are also studied, including temporal synergy, spatial synergy, process synergy and environmental synergy. The backfill storage is identified as a new type of reservoir, divided into three types by functional characteristics, i.e., backfill solid storage, backfill gas storage and backfill petrol storage. Based on the size and shape characteristics, three types of backfill storage are classified as below, i.e., with square, cylindrical and ellipsoidal shapes, and their respective characteristics are also studied. Taking the backfill petroleum storage as an example, this paper studies the characteristics of backfill storage structure and the functional backfill material with high strength and low permeability, describes the series-parallel structure characteristics of backfill storage group, and determines the working principle of backfill petroleum storage. In addition, this paper analyzes the stability of backfill storage, establishes the safety distance criterion for backfill pillars, and deduces the calculation model for the roof loading of backfill storage.

Key words: backfill mining, goaf utilization, MBS synergetic system, backfill storage, stability
