Act No. 61/1988 Coll. on mining activities, explosives and the State
Mining Administration, as amended by Act No. 542/1991 Coll.:
The subject of the edit
(1) this Ordinance has been notified in accordance with the directive of the European
Parliament and Council Directive 98/34/EC of 22 December 2004. June 1998 on the procedure for the provision of
information in the field of technical standards and regulations and of rules on services,
the information society, as amended by Directive 98/48/EC.
(2) this Ordinance regulates safety and health at work and the
safety in the mines with the dangers of mining shocks. ^ 1)
Interpretation of the terms
For the purposes of this Ordinance shall be construed as
and mining shock) (hereinafter referred to as "concussion")-the natural phenomenon of sudden violation of
the Massif, which is reflected by a sudden pull or an expulsion
rocks in the mine with as a result of his obvious and permanent deformation;
This phenomenon may be accompanied by seismickým and sound effect in this
mine workings. In this storyline, gaseous and liquid components contained in the
mountain massif are not participating significantly. In the place of release of the flexible
energy and violation of the Massif is divided into slojové shock and aftershocks of the
the higher the overburden,
b)-a shock phenomenon natural phenomenon of sudden violation of the Massif without
deformation of mining works; a Concussive effect shall be popping and

(f) regional forecast)-summary of activities to establish
susceptibility of the parts of the Massif, its layer units, seams or
their parts to the formation of shocks on the basis of the evaluation of the natural conditions
and the assessment of the occurrence of shocks in analogous conditions
(g)) the local forecast-summary of activities include mining work
to the degree of danger of upheaval, already at the stage of planning and design,

that may be based on the regional forecast shock.
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
the work place (function) geomechanika occupied by an employee of the organization with
graduate education laid down by a special legal regulation ^ 4)
at least three years of mining experience in mines with a risk of shocks.
(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.
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.
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.
(2) between the mine workings in the 1. the degree of risk of shocks are classified
and all mine workings) led off the seam,
(b)) long mine workings in the sloji of powers to 1.2 m with přibírkou
the accompanying rock
(c) the mine workings in the sloji), whose leadership is not expected to rise
(3) between the mine workings in the 2. the degree of risk of shocks to be classified mine
the works, whose leadership cannot be ruled out the risk of concussion.
(4) between the mine workings in the 3. the degree of risk of shocks to be classified mine
the work, which can be when their leadership to assume the risk of
the Jolt or the leadership to the seismic shift has already occurred.
Forecast the formation of shocks
(1) in the mines with the risk of shocks should be well in advance
to carry out regional and local forecasts and to detect and
evaluate the necessary information.
(2) the Regional forecast is used to delimit parts of the Massif, where
There is no danger of upheaval.
(3) the basis for the regional forecast are natural data on the bearing and
parts of the Massif in relation to slojím planned to conquest.
The main data are reviewed, in particular,
and sandstone lithology, vrstevního)
b) physico-mechanical properties of coal and rock
(c)) the depth of the deposit under the surface, the power and the layers of bows,
(d) structural-tectonic structure).
(4) the Local forecast is carried out in parts of the Massif with danger
the formation of shocks. On the basis of the results of the local forecasts with the workings
classified into 1., 2. or 3. the degree of risk of shocks.
(5) documents for local forecasts are especially
and storage) ratios (for example, the depth of the deposit and the thickness of the seam),
(b)) the current mining activity (for example, the edges of the nevýrubů, left
the pillars, the presence of goaf areas, vyrubání protective seam).
(6) the interim forecast is carried out when the lead mines in parts of the
the Massif with the danger of the formation of shocks. The method of implementation of the interim
the plan provides for developing forecasts, training and mining. ^ 6) Position
the interim forecast, its frequency, the resources, as well as the use of their
the results of specifying the technological procedure. The results of the mid-term forecasts can
serve to the reassignment of the mine tunnels to other degrees of risk laid down in
the local forecast. The work of mining, in which the singing, always

c) seismic monitoring and evaluation.
(8) a part of the ongoing evaluation of the development is
seismic activity of the Massif in the wake of the data
about the seismic activity around the bearings, or the pelvis.

mining based on a long-term concept of mining activity and be with her in
accordance. ^ 8) the long-term concept of mining activity must be
the mines are processed each year, and with it the views of at least three years.
The concept of mining activities takes into account the long-term strategy
protiotřesové prevention and shall submit to the relevant district mining
the authority for regulation of the necessary measures. ^ 9) in concept it is necessary to choose
the procedure, which does not increase the risk of upheaval in the same or in a different sloji,
or part of the Massif, and does not hinder the use of the resource protiotřesové

terms and conditions. This update must be submitted to the district mining Office
to the regulation of the necessary measures. ^ 9)

already in developing the plan, the preparation and development of ^ 10) the appropriate seam.
Coordination of work
(1) the mining activity in the mines with the danger of upheaval in their parts and
also between neighbouring mines must be coordinated and
(2) the procedure for the work of two or more down on mining areas ^ 11)
These must be discussed in advance by racing down and agreed. ^ 10)
(3) the coordination of the work on the mining areas shall be
