### Research on the Relationship between the Extent of Damage Intensity Index and Mining Impacts
#### 3.2.1 Dependence of Damage Intensity of Large-Block Buildings on Mining Impacts  
The results presented in Table 5 show significant correlations between horizontal ground deformations \(\varepsilon_{max}\) and indices:  
* Intensity of damage to interior and exterior overground load-bearing walls (including lintels and walls under windows) \(w_{u3}\),
* Intensity of damage to ceilings over higher levels, flat roof (roof covering) \(w_{u7}\),

The results of correlation tests between maximum acceleration components \(PGA_{H}\) and damage intensity indices has only showed significant correlations for floors \(w_{u13}\) and facade layers \(w_{u17}\).  
The highest correlation coefficients with values of \(R=0.501\div 0.853\) were obtained between the \(a_{sg}\) index describing the influence of mining tremors and the damage indices of all significant elements.  
In addition, for the horizontal ground deformations \(\varepsilon_{max}\) and the mining tremors index \(a_{sg}\), significant correlations were found with the \(w_{u}\) index determined for the whole building, which are 0.145 and 0.866, respectively. The significance level of the \(PGA_{H}\) index was close to the critical level (\(p=0.05\)).
