Dramatic mine injuries early in 2006 have resulted in passage of the 1st significant modification to federal mine protection legislation for the reason that 1977. The Mine development and New Emergency reaction Act calls for each one mine to have an emergency plan, elevated offers of oxygen, and enhanced rescue groups. consequences for violations have additionally been elevated. even if the invoice had large aid in Congress, a few contributors have characterized it as just a 'first step', to be through extra measures that might comprise a decrease greatest restrict on dirt concentrations, underground refuges, communications and monitoring units, and bigger emphasis on enforcement of criteria. On January 2, 2006, the kingdom used to be reminded of the hazards of underground mining, as 12 miners died in an explosion and hearth within the Sago mine in West Virginia. hence, the Mine security and future health management (MSHA) issued new laws; Congress has handed the 1st significant revision of the mine security legislations on the grounds that 1977 and has taken extra accounts into consideration; and, kingdom legislatures in West Virginia, Kentucky, and Illinois have tightened their very own legislation. those responses have emphasized components inspiration to have performed an element within the Sago tragedy, together with emergency oxygen provides, monitoring and communique platforms, and deployment of rescue groups. There have additionally been proposals to extend the consequences for violations of security criteria.

Administration of the Survey We used a self-administered mail-out questionnaire that was in the field between November 2006 and February 2007. We conducted several follow-up efforts to encourage a higher response rate: a reminder letter, a second mailing that included another copy of the questionnaire, and two efforts to contact nonrespondents by telephone. We ended data collection in February 2007. Nonsampling Error and Data Quality The practical difficulties of conducting any survey may introduce errors, commonly referred to as nonsampling errors.

The MINER Act addresses some of these issues, and underscores NIOSH’s and MSHA’s roles in developing and approving safety technologies. For example, the act requires NIOSH to establish a permanent Office of Mine Safety and Health in order to enhance the development of new mine safety technology and speed the use of such technology in the mines, some of which requires MSHA’s approval. The act also requires NIOSH to study the use of refuge chambers for miners that are unable to escape a mine during a disaster and requires MSHA to review the results to determine what actions, such as making regulatory changes, are appropriate in light of NIOSH’s findings.

Finally, we referred to the recent mine evacuation regulations developed by MSHA and the Mine Improvement and New Emergency Response Act of 2006 to ensure we were collecting timely information on the operations at underground coal mines. A copy of the survey questionnaire can be found in appendix II. To verify the clarity, length of time of administration, and suitability of the questions, we pretested the questionnaire with mine safety officials at three mines. We revised the instrument based on the results of the pretests and the feedback we received.
