Through static description of the filling mining geological environment, analysis of overlying strata movement law, closed loop control of mining effect and establishing scientific system of filling mining theory and technology, etc., filling mining theory and technology research and development direction were settled. According to filling mining strata control theory, static description of geological environment, the dynamic monitoring of overlying strata and filling body, filling mining automation and low cost of filling materials, etc. were studied to improve the systemic of the research and form a complete filling mining pressure theory system, combined with laboratory test and engineering practice, made filling mining a mature mining technology.
