Ground Control
Program
• It consists of drawings, plans, specifications or procedures. Must be prepared under the direction of a competent person and be based upon sound geotechnical engineering practices. It must describe: – geology – excavation geometry – previous ground problems – mining methods – assessment methods – ground support
• The mine design must be updated annually and also before any alteration is made to the mine that may significantly affect the ground stability of the mine.
• A copy of the mine design must be available for review by an MOL inspector and by the JHSC.
Sect. 6 – Mine Design
Refer to Ontario Regulation 854 at http://www.e-laws.gov.on.ca/html/regs/english/elaws_regs_900854_e.htm
• A Professional Engineer’s report is required if:
– the geometry of an existing excavation that does not have ground support is to be altered
– a new excavation is planned to have no ground support
• The report must be prepared in accordance with good geotechnical engineering practice.
Sect. 6.1 Unsupported Underground Openings
Refer to Ontario Regulation 854 at http://www.e-laws.gov.on.ca/html/regs/english/elaws_regs_900854_e.htm
• A pillar 60 m thick must be established between adjoining underground mining properties.
• Before the pillar is mined, drawings, plans, specifications, mining methods and procedures must be approved by a professional engineer in accordance with good engineering practice.
• Pillar dimensions and mining methods and procedures must provide ground support to control ground problems and must withstand the inrush of water or materials across the party boundary.
Sect. 19 Boundary Pillar
Refer to Ontario Regulation 854 at http://www.e-laws.gov.on.ca/html/regs/english/elaws_regs_900854_e.htm
Sect. 65 – Program for communication of ground control information
Refer to Ontario Regulation 854 at http://www.e-laws.gov.on.ca/html/regs/english/elaws_regs_900854_e.htm
• A written program for the timely communication of ground control information must be developed in consultation with the JHSC.
• The program must describe:
– The means and procedures for communication
– The kind of information to be communicated
– The actions to be taken by supervisors with respect to information that is communicated to them
Refer to Ontario Regulation 854 at http://www.e-laws.gov.on.ca/html/regs/english/elaws_regs_900854_e.htm
Sect. 67 – Procedures for Ground Control
• Written procedures must be prepared for activities relating to the installation of ground support and activities that require a worker to be exposed to unsupported ground.
• The procedures must describe the methods for preventing workers’ exposure to unsafe ground conditions.
• The employer must consult with the JHSC in preparing the procedures.
• A written record of a rockburst or uncontrolled fall of ground must be maintained (time, location, extent, any injury, and other relevant information such as monitoring data).
Sect. 72 – Record of rockburst or fall of ground
Refer to Ontario Regulation 854 at http://www.e-laws.gov.on.ca/html/regs/english/elaws_regs_900854_e.htm
Sect. 21 Notice of unusual occurrence
• A notice in writing must be given to the Ministry of Labour for:
‒ A rockburst causing the displacement of more than 5 tonnes of material or damage to equipment
‒ An uncontrolled fall of ground causing the displacement of more than 50 tonnes of material or damage to equipment
• A quality control program must be developed to ensure that ground support specified in mine design must be well installed and remain effective while in use.
• A record of tests conducted under the quality control program must be maintained.
• If requested, the employer must provide a copy of the program and a record of the tests to the JHSC.
Sect. 73 – Quality control of ground support
Refer to Ontario Regulation 854 at http://www.e-laws.gov.on.ca/html/regs/english/elaws_regs_900854_e.htm
