Nowadays, the functioning of mining companies is conditional not only on the market situation, but also on the good relations with stakeholders. Good relations with recipients, suppliers, employees as well as with local communities and environmental organisations are of crucial importance. Social acceptance is becoming one of the primary conditions for mining operations. The main complaint faced by mining companies is their negative impact on the environment. It is, therefore, important to determine not only the measures aimed at reducing the negative impact of mining on the environment, but also the amount of expenditures allocated for this purpose. The main aim of this study is to analyse the investment outlays allocated for environmental protection. In order to support the aim of the study, a statistical analysis of data from 2003-2016 was carried out in terms of the structure of outlays for environmental protection: air and climate protection, water and sewage management, and soil protection, as well as protection against noise and vibration.
