§ 3



The management of protiotřesové prevention



(1) ^ 2) must ensure the prevention of protiotřesovou. Organization

a uniform procedure and management of protiotřesové prevention in coal mines

the release of the guidelines (working rules) ^ 3) following consultations with the district mining

the authority and lays down the organizational measures to ensure the fulfilment of the obligations

imposed by this Decree.



(2) to control the protiotřesové of prevention must be specified on every down

(3) the Geomechanik must the competence for the performance of functions prove

examination before the Commission of the district mining Office.



(4) The mines with the danger of upheaval, that make up the organizational unit

the workplace must be established, which continuously monitors and evaluates the

seismic activity in the area. In the case of interruption

the work of mining in a mine can interrupt the continuity of the racing mine

evaluation for the mine. However, the evaluation must be performed

before the renewal of mining work.



§ 4



The classification of parts of the Massif



In the mines, with the risk of shocks are considered to all parts of the Massif

dangerous shocks if they are not on the basis of the results of the regional

the forecast included as part of the Massif, without the risk of shocks.



§ 5



The classification of mine workings



(1) All led by mine workings with the exception of those that are included in the

parts of the Massif without risk of shock, racing down ^ 5)

According to the results of the local forecast to 1., 2. or 3. the degree of danger

shocks. This may include only part of the mine workings.
