熟料含量对矿井充填胶固粉质量影响研究

为了减少对自然环境的破坏,保证充填体强度,节约充填胶固粉生产成本,对胶固粉配
比进行优化试验。通过调整胶固粉中辅料与矿渣配比以及辅料中熟料与石膏的配比,测试不同熟料
含量的充填体试块 3,7,28 d抗压强度,研究熟料含量对胶固粉、充填体试块的性能影响。试验结果
表明,适当降低熟料含量能提高胶固粉前期抗压强度,并对后期强度影响较小;当石膏含量提升至
17.4%、16.8%,熟料含量降低至1.2%、1.8%时,充填试块的前期强度达到最优值;在相同养护龄期下,
辅料与矿渣配比为 20∶80,熟料掺量为 1.8% 的充填体试块整体抗压强度最优,可使胶固粉单位生产
成本降低约3元。

Study on Influence of Clinker Content on Quality of Mine Filling Cement Powder

In order to reduce the damage to the natural environment,ensure the strength of the back⁃
fill and save the production cost of the filling cement powder,the optimization test of the formula of the ce⁃
ment powder was carried out. By adjusting the ratio of auxiliary materials and slag in cement cement and the
ratio of clinker and gypsum in cement cement cement,the compressive strength of backfill test blocks with
different clinker content at 3,7,28 days was tested,and the influence of clinker content on the performance
of cement cement and backfill test blocks was studied. The test results show that appropriate reduction of
clinker content can improve the early compressive strength of cement cement,and has little influence on the
later strength. When the gypsum content is increased to 17.4%,16.8%,and the clinker content is reduced
to 1.2%,1.8%,the early strength of the filling test block reaches the optimal value. Under the same curing
age,the overall compressive strength of the backfill test block with the proportion of auxiliary materials and
slag of 20∶80 and the clinker content of 1.8% is the best,which can reduce the unit production cost of ce⁃
ment by about3yuan.

Abstract:

In order to reduce the damage to the natural environment,ensure the strength of the back⁃
fill and save the production cost of the filling cement powder,the optimization test of the formula of the ce⁃
ment powder was carried out. By adjusting the ratio of auxiliary materials and slag in cement cement and the
ratio of clinker and gypsum in cement cement cement,the compressive strength of backfill test blocks with
different clinker content at 3,7,28 days was tested,and the influence of clinker content on the performance
of cement cement and backfill test blocks was studied. The test results show that appropriate reduction of
clinker content can improve the early compressive strength of cement cement,and has little influence on the
later strength. When the gypsum content is increased to 17.4%,16.8%,and the clinker content is reduced
to 1.2%,1.8%,the early strength of the filling test block reaches the optimal value. Under the same curing
age,the overall compressive strength of the backfill test block with the proportion of auxiliary materials and
slag of 20∶80 and the clinker content of 1.8% is the best,which can reduce the unit production cost of ce⁃
