摘要

朱村礦進(jìn)入后期生產(chǎn)后,可采儲(chǔ)量少,村莊建筑物下呆滯儲(chǔ)量多,為進(jìn)一步挖掘儲(chǔ)量,延長(zhǎng)礦井服務(wù)年限,采用膏體充填開采技術(shù)。理論分析了朱村礦充填開采后隔水層厚度和底板最大破壞深度,根據(jù)朱村礦的地質(zhì)條件,選擇了合適的充填材料及充填工藝,并在54采區(qū)進(jìn)行工業(yè)性試驗(yàn)。實(shí)踐表明:工作面采用膏體充填后,巷道頂?shù)装遄冃瘟啃?工作面直接底破壞深度小于5 m,能夠有效防止底板L2灰?guī)r強(qiáng)含水層突水,隨著充填技術(shù)的成熟,地表沉陷量逐漸減小,地表建筑物的破壞控制在Ⅰ級(jí)范圍內(nèi),充填效果良好。
        During the advanced production stage of Zhucun Mine,the recoverable reserves lessens while the sluggish reserves under village buildings becomes more. Thus,the paste filling mining technology is adopted to achieve more reserves as well as extend the service life of the mine. The paper theoretically analyzed the aquifuge thickness and maximum floor failure depth of Zhucun Mine after filling mining. It selected the appropriate filling materials and filling process according to the geological conditions of Zhucun Mine,and carried out industrial test in No. 54 mining area. Practice shows that after using paste filling,the deformation of roadway roof and floor on working face is in a small amount,while the direct bottom damaging depth of working face is less than 5 m. Through this,the water inrush of roadway floor L2 limestone strong aquifer can be effectively prevented. As the filling technology develops,surface subsidence volume decreases gradually,the damage to the surface buildings is controlled within Grade I range. The above test results prove good filling effect.
