should be provided to the roof control supervisor as soon as practicable.
(Refer to Methane Test Ext Cuts: 68 Fed. Reg. 40132 (July 7, 2003) for additional
information.)
Documentation Required: Roof and Rib observations should be documented in the
inspection notes to show the MMU number, and that the roof and ribs appear
adequately supported. If geological conditions that are abnormal to regular mining
conditions (faults, interfaces, etc.) are observed, they should be noted. A general
statement about the discussion held with miners for each MMU inspected about
current mining activities and conditions, and training with respect to the roof control
plans is adequate; focusing especially on training with respect to retreat mining
activities will suffice.
17. Sanitary Facilities. Sanitary facilities located on a working section shall be
inspected for compliance with §§ 75. 1712-6 (Underground sanitary facilities;
installation and maintenance) and 75. 1712-10 (Underground sanitary facilities;
maintenance). Special attention shall be given to the location and cleanness of
these facilities. (Refer to Sanitary Toilets: 68 Fed. Reg. 37082 (June 23, 2003) for
additional information.)
18. Section Equipment. The inspector shall compare the mine operator’s record
of weekly examination of electrical equipment to electrical equipment in use
and available for use. All electrical equipment in use and available for use
should be maintained and listed in the ITS. An inspection shall be conducted
of each piece of in use and available for use electrical equipment as listed in the
operator examination records or observed in use by the inspector to determine
compliance with applicable standards and to determine if hazardous or
potentially hazardous conditions exist, with attention to permissibility, safe
access, guards, equipment condition, fire suppression systems, combustible
materials, fire protection, condition of trailing or inter-machine electrical
cables, cable conduit, circuit breaker capacity and identification, methane
monitor, and safety devices. Each piece of in use and available for use portable
electrical equipment should be inspected. The inspector shall assure the circuit
breaker, receptacle, and plug is labeled to be the same. On at least an annual basis
electrical specialists or inspectors who hold a current MSHA electrical qualification
card should conduct a complete permissibility inspection of each longwall system. If
an inspector finds that wiring of electric equipment is in a rundown condition,
with many violations existing on one unit of equipment and if there is
evidence that thorough and complete examinations are not being made or that
the required tests are not being made, a citation should be issued under
§ 75.512 (Electric equipment; examination, testing and maintenance). Please
refer to the Coal Electrical Inspection Procedures Handbook, Chapter 2, for
more information. Inspectors shall not attempt to perform inspections or tests
